This show stirs up nostalgia. Feels like a 1998 Saturday morning

This is insane. Can't believe this thing has been around for a decade and I hadn't ever hear of it.

Actually have been building these for over a decade now, we even built a Magnuson supercharged version that made 755 lb-ft of torque. Coil on plug ignition with a FAST ECM. If you have any questions on how we did it just reply here and I will send you some info! The engine was featured in the August 2011 issue of Muscle Car Power Magazine. There is also an article in LSx magazine.

Man...that older guy always sounds like he's hammered

They should have made LS heads fit the sbc. Would have sold more..

Those lifters and rockers are fresh, fresh on their way out with the way they sounded on those runs. Ouch !!! Would not want my engine sounding like it's got a half a quart of oil in it lol.

To me the only purpose for this set up is a hot rod that you already have a small block in and don't want to redo the motor mounts, and fab work!

Nice to see you on the screen again. 👍

A prom programmed for your engine? Damn aged itself hard there 😂

36👍's up HP thanks again for taking us all along with you

This episode comes to mind sometimes and I haven't seen it since it aired. Thanks for the upload

Awesome video! Love the way you guys do your videos. And also keep the awesome weird stuff coming Motown! Always wanted to do this same kind of thing…

They make these things called swap mounts. Craziness

Thank You! Awesome Motor, and Build!🔧🔩🇺🇸

I LOVE IT!!!! TOTALLY AWESOME UPGRADES!!!! THANK FOR SHARING111

This is GREAT. The old small block V8 not only lives but gets a tech upgrade.

Nice sewing machine. You guys nailed it 👌

I like how it has a lifter tick right outta the box

My small block I used Eskandarian camshaft along with their anti-pump up lifters works like solid lifters but hydraulic bad ass, my 327 is now up-to-date as far as that goes turbo 400 Street shift kit 373 true track rear end. In a 1940 Ford deluxe two door coupe! Yeah.

Perfect combo

Looking good bud if you get bored we have an event down here in Montana June 27th

AWESOME ENGINUIEDY GREAT JOB 👍 GUYS

After all these years struggling with gaskets they finally making a decent gasket

I love that small block

That’s a cool half breed engine love it best of both worlds

Wow! Can't wait for the next episode... overhead valve conversion and LS style heads for the flathead Ford!!! You're killing it, World Products!

I got a 383 with forged pistons and Afr heads. I already know how to spend a fortune.

I think it’s a cool build, but I would’ve used different lifters that’s for sure. Morel, Jesel or Crane, had to many problems with comp stuff, and I’m not the only one either.

Congrats on 100k subs

I knew it, I knew it! Someone was going to do this!!

Powerful combination 👊🏾💪🏾💯

Seems like a lot of trouble and expense for the privilege of keeping the distributor

This is a really great hybrid engine.

I’m guessing that new block is worth more than a good running LS.

I ALWAYS ran Cherry Bomb glasspacks on my GTO i do love the sound!!

Funny how they say the reason to buy this block is so you can run a distributor, then they show an LS motor that has a distributor driven off of the timing chain mounted to a modified timing cover to do their muffler test.

Sounds like you have some lifters taping. Nice hp tho. 🔨

Very cool if you need it.

I KNEW they had built one of these. Of course people said I was stupid but I have been a PowerBlock fan since before they were ever called PowerBlock.

No exaggeration , those Pro system SV-1 single blade carbs are super Snappy, i have heard transmission input shafts snapping and driveshafts breakage. An incredible part. Note this airing of episode was 2010 i have learned from the comments below.

I'm not the only one that heard it knocking like a jw on Saturday morning, am i?

It’s great the aftermarket continues to support the SBC! Chevy engineers addressed many of the limitations when designing the LS1. Versions that followed such as LS3 are even more advanced. Pretty easy to make 600 hp at 376 ci with LS, and street manners like it’s not even modded. Think what it takes to equal that with a 383” SBC, and it weighs at least 100 lbs more than the LS3.

RIP Joe. You will be missed.

Well if you can fit ls heads on a 351w with little modification. .it's no surprise the sbc can get ls heads too.

Is it just me or is the lifters already tapping? Lmao

Super impressive 👏

Wow I like it 👌

Man! A SBC with LS heads. YESSSSSS.

If that's all anybody can complain about us a sound of The lifters think the whole conception is a fantastic idea I am old school but I think that combination is awesome with some really nice parks

Crazy to build this caliber of engine with a cast iron timing gear, i dont even use them in stock engines anymore since ive found 3 cam gears cracked with nothing more than a valve spring upgrade. Luckily they chose to do a cam change soon after spring upgrade

They do all these projects but never fess up to what it all costs. For the price of the special block and crank along with the rods pistons cam and lifters, you could probably build at least two 600 hp LS motors to put that set of LS heads on.

If they wanted to get 5 to 8 more horsepower they should have installed a 1 inch carb spacer plate only because those butter flys on the carb should be above to top of the runners and not even with them , also they should side gap all the plugs to expose the spark directly to the combustion chambers .

Looks interesting but what do you do when it comes time to bolt your accessories on? Appears cylinder heads and coolant tubes will cause issue?

Mind blown!!!😳🤯😵

I haven't seen anything like that at car shows at all wonder how well them sold

I had this 66' Bel Air station wagon with a vortec head swapped 327. I took it on down to the local muffler monkey & handed him a pair of single chambers and to install full 3" exhaust exciting behind the rear tires. How loud could it possibly be ??? I'll tell you this brother...ever been to a cackle fest ??? Holy Crap !!! & We had one hour to check the car in at Street Rods North (NSRA) we had to put on hearing protection just to drive it down the highway !!!! Learned my lesson 😆

Neat, money money money. That being said it sounds like the 53 year old 292 in my farm truck. Makes decent power though I just can't get over that lifter sound.

Think they'd make them the other way around but I guess we can't argue with progress??? Why don't they just re-design a LS style head to fit any stock small (block) bolt patterns. BUT I'm sure there's plenty of other issues with cooling flow and other minor things.

Now this is a awesome setup. But can you hookup say alt p/s and a/c to it with factory mountain brackets???

My favorite engines am i glad they did this episode!!

Can make the same power with a decent set of heads and matched retro fit roller cam + intake / carb combo. This setup is a joke unless you've got more money than sense

A conversation piece is the only benefit of this I see lol. Even a stock junkyard 5.3 will handle more power than 90% of SBC’s so why use a SBC bottom end.

without the long skirt of the ls block, these will actually make more power over a comparable ls motor since windage is vastly reduced

That big single blade carb reminds me of an old predator single

Then there's guys like me with open pipes😁

Accessories, accessories. I would have put those adapter plates near the rear of the motor and snuck a return pipe under the manifold attached to that valley cover. Why... I might even be able to stick with oem radiator hoses. This build could put alternator and power steering down low but I want my air conditioning - damn the critics!

That's a nice Holly predator

This concept seemed quite interesting and feasible ay the time, but it never seemed to catch on. We do roughly 80 to 90 builds each year, and we're building many small blocks from 383 to 427 and even a couple of 434's. As well, we do a few LS motors, but we've never had anyone approach us for this Chevy/LS combo. World Products produced a 1st gen block with the LS bolt pattern decks, and I expected that idea to gain some speed. The selling point was fitting LS technology into early Chevys without having to modify the crossmember and engine mounts etc. Now that several companies offer beefier LS blocks, no one seems interested in mounting LS top ends on early blocks

Id be dancing on that motor too she look good !!!!

Why do everyone think that lifters are like a spunge and 'soak' them for a time before assemble? Yes, they are 'hollow', and soaking them might not ensure the air to get out. But when priming the oilsystem with a drill while turning the engine slowly it will get the air out, and.. suprise! lube them also :)

I like it all

Looks like you can get to the lifters without taking the heads off. A great advantage for racing.

What would be the bill for a kit like this. Everything you have shown? Thanks much. I thought by now one of the head manufacturer would have come up with dual over cam heads? Would take some extra machine work to mount a cam drive system but could be maybe de stronger than a coyote. Thanks for this video.

The “Secret” to the Ls engines power potential is in the heads. Factory LS heads flow the kind of air that big dollar aftermarket heads do for the gen 1 sbc. So those who say that a decent set of heads on a standard small block is every bit as good as an LS, doesn’t understand the limitations of the og small block (max cam lift especially when using a hydraulic roller, cooling issues especially with the siamesed exhaust ports). these are really only limitations when compared to modern engines ie the LS, a small block can make more than enough grunt for the street, that power is just easier to produce with an LS

The lifter noise😳

I love it 😀 😍 ❤

sounds like a diesel at idle there lmao

I used to think these blocks were a good idea. But it turns out stock internals are just fine on engines without detonation problems and the ls parts are well designed. While the sbc has an oil pump that doesnt eat much power the ls has ventilation between cylinders, larger cam core, a cross bolted skirted block for noise rejection and main cap stability etc... The ls has proven that the importance of a forged crank in anything but a split pin v6 is highly over rated and if you don't have to buy racecar parts then why do it? The aftermarket has addressed the oil pan situation and the lack of a distributor and even with the hybrid block headers are still a consideration and now brackets can be an issue where they wouldn't be with a true full ls. I mean if you just love distributors mechanical fuel pumps it might seem like a good idea but for the cost of an aftermarket block you could just buy afr heads and keep the 23 degree setup. Heck you could but 15 or 13 degree race heads or some used sb2 or 18 degree heads.

This is just a custom cast and milled gen 1 small block Chevrolet. People are wanting to do this with junkyard blocks but without having to mill it.

That sound, though...!!! Different than a small block or an LS

An sbc with Ls heads is a great idea until you realize you can't mount accessories with the coolant crossovers in place.

Should be epic with a small journal crankshaft.

Easy roller cam conversion by just using the cam and lifter kit on any old 350 block you might have in your backyard. 🤔🤔

No real advantage to the hybrid motor. Get some aftermarket heads that outflow the LS stuff and build a SB shortblock. Less expensive and easier. Hard to beat the old SB.

This video is at least 13 years old, I saw originally on when it was spike TV.

Please check the Dynomax Race Bullet mufflers.

Awesome but money's no object to you guys I like your show could you sponsor me in a build?

Disturb the peace, I wonder how much that engine cost

Nothing in common with the old SBC but alot in common with a and 351w. Thrust bearing in the center, equal length ports, and same head design with 10 headbolts. I work at a machine shop for a living so I know.

And here I’ve been thinking all the buzz was in the mains! 😬

Cool but I will stay with my gen1 bc I don’t make 100k a year

A lot of seams in that coolant crossover and where does the belt-drive go?

Sounds like it is going to come apart with all the rattling in it .

Forgot how old this episode is. We don't have to do this to run a dizzy on an LS anymore.

That thing is ticking like crazy! Sounds like a sewing machine.

Sorry guys. We get rectangle port 6.0 core motors for $500. They have 4bolt mains with 2 more crossbolts from the oil pan rail. A msd ls box is about $450. This video is a waste of money

I'd guess the Gen 1 SBC lower end would be worth around 25-30hp, due to the LS engine having issues with bay to bay breathing.

Interesting 🤔

The glass pack is the loudest. Run it for a bit and the fiberglass blows out and it becomes a straight pipe. Alternatively pour some gas in it and light it to burn off the fiberglass before installing.

Please explain how you three-quarter pipe a 10 bolt head put on 17 head bolt block
