Why? So you can lose low end torque?

@@christianmotley262 Cam choice is always a torque/horse power trade off. I have no problems breaking the tires loose on take off, solid shift into second produces complaints from tires again. My 4.3 is far from stock, 10.2 compression, larger valves and ported heads. That being said, Yes I would trade some low end torque for more high end horsepower.

Starting build of 4.3, what did you do to yours? Frost

@@elreyyakko Crankshaft was ground and indexed. Block bored .030 and decked slightly to match both sides and ensure the deck was 90 degrees from each other. Mains were line honed. Factory rods were clipped and resized, pin end bushed, then balanced. Full groove main bearings and Manley high volume oil pump. Heads were cut for hard valve seats to receive the 2.02 intake valves and 1.60 exhaust valves. Several hours spent smoothing up the ports and matching them to the intake manifold. Milled heads and cleaned up combustion chambers some plus cc'd Manley stainless steel valves, replaced valve guides with bronze inserts. TRW forged pistons with slight dome, result was 10.0 to 1 compression. Double moly rings, both top and second ring. Pro Comp 266HR Cam as I previous stated I wish I'd used the 270H Pro Comp hydraulic roller lifters. Pro Comp Valve springs recommended for the cam. Pro Comp steel valve spring retainers and keepers. Pro Comp Magnum full roller rocker arms with locking nuts. Cloyes timing chain and gears. Chrome moly pushrods. Replaced poppet injectors with GM upgrade to actual injectors. Reprogrammed computer, I own an EFI Live programmer BBK throttle body and aftermarket MAF (no screen) If your curious about this let me know and I'll go look and see what it is. Aluminum body distributor and MSD ignition. Transmission was fully performance rebuilt including a 2500 rpm stall converter I worked in a speed shop for many years. When I did this build I used a friends speed shop that had all the equipment. I really enjoy driving this truck, it's now over 22 years old. (built Oct 2000) Let me know if you have questions, I will try to answer them.

@@frosteone1670 nice! I plan to go with 2114 edelbrock intake and carb, and compresion at 10.5, heads are my main headache,since cant find info on valve size but now thanks to you know i can go 2.02/1.60. Seems Im more or less doing your build but going with the 270 cam. Truck is bigger, its my dads 90 1500 cheyanne that we restored. Trans is done and exhaust/headers. Rear im thinking 3.23 since its for cruising and car shows. Would love more info on your build. Ive got my channel and i think we can send messeges that way.

Awesome, thank you Jacob !

94-04 will all be the same room. 93 and below is square body

Very interesting man. I never would have thought that you could use a tranny and be able to rock the standard driveshaft. Only other thing would be a wiring harness I'm guess and a tune. I'm just gonna build my 4.3

That's what I want to do with my Jimmy. It's not a heavy truck, and I don't want to be yet another guy who did a 350 or LS swap.

Projecting

Good luck finding a Marine intake much less big bucks. I wanted one also for my 350 too as is tbi but going to have to go carb cause of that 325hp engine build I did. Can't afford a $1,200 aftermarket tbi thats ust basically a carb anyways.

factory computer and after market cam's don't mix will. just so you know

They do if you program the cpu. Also the cpu does program itself slightly too.

@@mobilemowers wrong.

@@mobilemowers older ECMs aren't that.

​@@kingjeremysircornwell7847lol....😂

I don't recall. I used the stock heads of the 1998 S-10 4x4 Blazer.

Everything in my build is proformance.Like the lifters, timing chain, oil pump and Vortec heads are proformance ( which can be ported). The same parts from a 350 interchange for the most part. Sorry for late responce I just do this as a hobby and for the past few years of this never made one dime from you tube. They did that 1,000 plus subscriber bs.

20 lbs at idle is well within limits. Would not worry till it drops below I 8PSI or so

¿What did the cyclone or typhone have for heads? that seamed to be high tech good flowing too.

You are so welcome!

The marine intake's are rarer and $$. What computer you going to use then ? Snipper is a throttle body kinda of going backwards. Also how you going to control the dash and trans ? Big bucks your talking. Being thrifty if you upgrade to the upgraded spider injectors you should be ok. Factory computers are ok if you know how to tune them. Can even send them out for a tune or use a canned tune. The factory computer can tune themselfs a little bit also. I know someone running 70ish Camero w a turbo runs in the 7's using a LS engine with a factory gm computer. Sniper is only throttle body so you loose some power vs multiport. Carbs are cheap and easy. Google EFI 3x™ 4.3L V6 also. Here is using the boat intake www.fullthrottlev6.com/forums/showthread.php?50198

Torgue is all in the cam and the intial timing for the cam. My cam is for more bottom end. Also convert it over to the 96/up multi port for more power an tunning.

Tourqe is not all in the cam forget this dude my 4.3 is almost done im doing more and less complicated then this mess ill be posting videos soon

@@codeack101wlck why don’t you make your own videos and stop promoting yourself so much an this guys Chanel while putting him down…. Instead of talking shit to get views why don’t you just make your videos better…. Have some respect

Trans will work fine same 40l60e as the pickups just a higher stall speed converter. The stock ecu and injectors should had that little cam. Try it first. No videos of it running a body shop has had it for 10 years ( yet paid) playing games with me on it. They blew up the orginal engine by letting gas down the intake thus why I just built another one.

Yes. You need to have the intake mouting holes redilled by a shop about $30-$40. Sorry for late responce I just do this as a hobby and for the past few years of this never made one dime from you tube. They did that 1,000 plus subscriber bs.

Or you can use the edelbrock 2114 intake and put a carb on it. 2114 fits vortec heads. 2112 fits pre vortec.

There's a stud out there that has the metric lower and 3/8 upper. Just have the stud boss cut flat. Haven't seen a way around it other than that.

Why not try the shorter poly locks like I did.

@@mobilemowers what was the part number? My builder couldn’t find any. I machined one down but the shoulders of the poly lock hit the inside of the roller rocker. Even with that my stock covers fit but probably would hit. Tough to tell just Turing motor by hand. I’m waiting on some 87-94 valve covers off eBay. I’m hoping they give me the room I need. 👍🏻

@@eddiemclean7011 Yep, that's the studs I used, Procomp rockers with poly locks, .500 lift cam and using factory valve covers.

As I listed in describtion of all parts. They were Silver lite 1436 pistions. Flat top, with four valve reliefs giving a 9.5:1 to ratio or so. www.summitracing.com/parts/uem-1436-030

@@mobilemowers Nice, Thanks.

If you want to spend more lot more money.

What is Edelbrock part # ? Thx

I called Edelbrock, they do not make valve covers for a v6

Valve seats cut down slightly if I recall. Also the springs in the video I show the box for Z28 spprings. Cause off almost 500 lift. Was like 2 years ago.

I am not a professional engine builder. I get my advice from my local shop from what I don't know. Talk to who is doing the machine work. I do know if your doing a turbo you want lower compression. Thats why guys buy used engines with miles on them and never do the rings. They already have low compression from use. If you use new rings you really have to open the gap. Power Block TV / Power Nation did a 4..3 Tubro build with over 300hp on KZfaq. Super chargers I think can do normal to little more then stock compression easy. They have super chargers that bolt right where the ac compressor would be, Google takes me to www.summitracing.com/parts/cca-12-704-8/make/chevrolet for a camshaft for boosted cars. Just be carefull and never go to high of a cam. You will loose bottom end. Been thier. You can call Comp Cams and ask them. Wait times can be crazy The 2003- 14 LU3 4.3L have injectors for each cylinder not the crappy spider injectors. They are like the 90's LT1's and the 99-up 5.3 ect Vortec's. Might want to swap over to that setup for guys with the older engines. Stock stall converters on a V6 already are higher. So use the stock one. Putting a VY convertor on a V8 will wake it up. Also the V6 trans can go in a V8 the parts interchange may tell you otherwise cause of the stall. I have V6 trans and convertor in my 94 K1500 w 350. Did video's on that. I also posted recently a video of the truck running, Hope this helps. Please like this video and maybe subcribe. Helps my video's and channels get noticed more with thier metrics.

Me too 85 v6 4.3

Well you don't use a roller camshaft.Your non roller camshafts won't be as cool with horsepower. You could do retro fit roller cam and lifters if you don't have cam retaining bolt holes in the block. Your tbi heads suck so you would need to change to Vortec heads and your intake as well.

I got it off eBay If I recall as was years ago. It was leaking out the back gasket when installed. I had a shop replace the engine was it was thier fault in the first place. They were so in a hurry I just got a cast iron one locally. Then they lose that alum water pump. Yet years later it is still in the same shop not finished. Sorry I don't check comments to often.

I can give all of you a full list of parts soon im in the middle of fully building my 99 zr2 blazer and love this engine great parts ill tell you now though your looking at spending 5k on copying my engine build

Had it all in the video with part numbers for the 98 year I did. Had under $1,200 or so into it. Cam shaft, true roller lifters,true double roller chain, preformance came shaft, head work, more compression pistions and better oil pump. Then will need a tune. Basics of any preformance build.

Yes got it running. The body shop still have it in their still doing nothing. Been in since 2012. That's why it needed the needed due to sitting. The injectors gummed up and the mechanic took the intake off and ran the pump. It then ran gas into the oil. Then rod knock happened almost instantly. I'll update it when I get the truck back and driving it.

@@mobilemowers hopefully it's soon just got a 02 blazer 4.3 wanting to build but I I due the middle cam due I have to reprogram the computer planning on putting a chip in it to override the automatic cut off and duel exhaust

They haven't used chips since 1995. Get a custom tune / hp tuners. Middle cam ? The ecm will reprogram itself for slight differences. Anyways best of luck.

Never really drove it but lot drove well so far.

Wait for mine looks like he gave up on it.

@@mobilemowers Hope you get this resolved - I’m looking forward to hearing your thoughts on the cam and power gains. I’m looking at either the 206 or the 210 myself.

Spent somewhere about $800. I did most of the labor. Never had it dyno tested. I gather almost 240 hp as stock is about 190.

Not sure your exact question with your broken English. I did this years ago. Think I used stock push rods if that is what your asking. Thats all I can tell you.

Look for mine soon 600+ hp

Be little under 300hp.

Yes still at the same body shop that blew up the old engine but taking off the intake and turning on the ingtion to see if gas was coming out the pump. The buttoned it back up wuthout changing the oil and the orignal engine instantly started knocking.

@@mobilemowers so it's not running?. I ruined my original 00' 4.3 Bought an 03' junkyard. Miles unknown Bought new injectors. Running great besides burning oil Roughly 100,000 miles later running.

Fuel injection due to emmissions and some better mileage.

mobilemowers I guess that works there’s someone who makes better heads for them but I can’t think of who though you can use also different sbc valve springs it’s just a 350 with 2 less cylinders

@@strengthstuff7618 he way over complicated this 4.3

@@codeack101wlck at this day in age it’s cheaper to go ls or mild sbc then trying to mess with the 4.3 I would have just did cam valve springs along with the carburetor and put a turbo on it should handle 7 to 10 psi and make 350 wheel horse

@@strengthstuff7618 no fun in that and would double the weight of my truck when all is done I've got the weight down to about 2300lb your looking at 4800lbs with the ls and drive train to go with it

either hydrolocked it or the gas thinned the oil. just a guess

When the shop was checking it for fuel pressure when the top intake was off lots of gas ran in the lower intake. At 60 psi or so a decent amount of gas comes out in 20-30 seconds. That gas mixed with the oil and got inbetween the rods and bearings. So gas got in the bearings and pushed the oil out. So run for a few minutes without oil and see what happens.

@@mobilemowers if it was in the shop, and they were testing it. And they caught it on fire and it busted a rod. Sounds like to me that shop just bought me a new motor

Never ever mentioned it caught on fire cause it never did. Just was knocking right after. I just built the replacement motor just to get it over with. The shop doesn't do the best of work.

Well it was during the build. Like a pre owned car nowadays.

Exactly you will have issues spring height w more weight, the engine ecu won't control the ls, with the dash working, factory, security controls the trans working and emissions controls.

@@mobilemowers You get it exactly! When the time comes to go that route, you will put both feet into it, and knock it out the park. I like to think previous projects are skill builders getting you ready for the next one. Go get er done, and have fun with your ride!

Vortec name came out about 1995. As far as I know the main improvement then was the heads. The heart shape chambers which flow better. The Vortec heads area great add on for a few hp for any pre 1995 engine. You may have to change the intake or have a shop machine the bolt holes. I have Vortec heads on my 1994 K1500.
