I'm just so ready for your dads tractor rebuild video. I love how you guys are showing it and are humble about what has happened. Most people would just blame the kit but he is going over everything he checked and even saying what he could have missed, you can't walk though the ranch and not expect to step in cow 💩 really once in a while. Also explaining what has happened.

It's great to see during your ad for the sponsor you displayed Blinker Fluid. One of the most over-looked essentials for any road-worthy vehicle. As a truck driver, I am amazed at how many vehicles on the road are dangerously low on blinker fluid, or they are using the cheap stuff from a discount store. Always buy a good quality blinker fluid from your local auto parts store!

Its so sad how many machine shops are closing, I bought a complete shop last year it was the ninth shop to go out of business in my area,l just couldn’t let it get pieced out. I worked in a shop several years ago but had moved into building street rods and sixties Chevys, so I guess I’m back to where I started. Thanks for your videos they are a great refresher so I don’t forget the little things.

I am a huge fan of this 396 rebuild. the baby big block always one of my favorite engines. nothing beats the sound of a 396 with a mechanical flat tappet cam. growing up in the mid 80, my uncle had an early 1970 Chevelle SS 396 L78 motor. that thing was amazing and incredibly fast. I am currently building a 1971 Camaro SS 396, but swapping i a hydraulic Roller with specs similar to the old L78 cam, but now a hydraulic roller simply because i want to be able to you off the shelf motor oil and not worry about the cam going flat, and I hate adjusting lash all the time.

Had a great machinist that I grew up around and taught me a lot, you and your dad have that same pride and attention to detail that my old friend had. He passed away and I moved, I've yet to find another machine shop near where I am that comes close to having his level of expertise. Kind of sucks having to cross state lines to get certain things done but I'd rather it done right than trade convenience for regret. You and your dad are part of a dying breed, true masters of a trade.

i think 🤔part of the problem for it becoming less is car's are disable/cheap to buy ( not explanation rather well sorry im trying ) but typical after about 5yo gets to be more expensive to owning vs just getting a new lease ( and as much as i like older car's some aren't worth it and or the metal has fatigued-out ect ) and the average person/30yo nowadays has more accesse to loaning/credit card's ect and spare income is lower and or most don't have 1k usd ( emergency's or disable/fun-planning-$$ ) to spending or the time needed bigger auto-repairs, heck i met people that moved out/sold their ( generally a newer home aka not 60+YO ) house just because of the AC broke/leaking ( aka sub 500usd repair or so ) , me im like okay big deal at least my "house" ( don't own anything property-wise aka forced sofar in to rental's and lower income's/slum-lord's one's at that ) is pay'd-off/no need to move and il get around to fixing it someday... and for me/88-90's-kid personally id rather have my engine 4.3X4.5"in D8-head's rebirthed but i don't have 10-30k usd that it needs to be 👌but so far iv been without my car/1969 charger for over a year now ( insurance was supposed to cover at least for the thefts/vandalism ect but so far im stuck paying for legalised fraudsters/insurance as they haven't paid anything yet 😡, i just wanted my car/dreams back not the debts or $$ or headaches from the joyriders that started the mess ) but even if $$ wasn't a problem it would have been at least 90+days as the shop has to order in and waiting and then i have to waiting for them ( and transfering thing's like heads and block aka heavy stuff that can't be mailed so id have to do it my self ect ) ect before i can R&R the engine-bay ect

That's 80 hours worth of grinding and testing I'll never get back. But it did add some power, I think, lol. We made 605 hp NA on the Dyno. If this one runs as good they'll need good tires. :)

Those intakes did look like they were begging for some work. I had those same heads with larger intake valves so the pockets could be blended and they worked really well. The Oval Port heads flow just fine for most street applications and if you build an 'enhanced' 350 horse 396 they'll surprise most people as long as you don't kill it with too much gear. Let the torque work and also don't over-cam for the 6000 rpm redline. I know it sounds really small for modern minds...but something 204/214 @ .050" and about 1/2" lift is more than the 350 horse 396 had stock and is enough to feed it while allowing it to make all the torque it can from idle up. Put a good 400 Turbo behind it and 2.41-2.75 gears and what a nice package!

@richb4099 Жыл бұрын

The valve guide and seat issues on an iron BB Chev are well known. I made the dumb mistake once of knocking out an exhaust guide from the top side down into the chamber side. Stock guides are different sizes on their OD's and stepped. Knocking them out in that direction can crack the head at the boss at the bowl side and may leak water. Sleeving the original guide is a much better way to go. GM did some really odd machining when they built those BB iron heads.....Just look at the guide holes and sometimes they are not concentric by a lot.....Just like how they located cam and crank centerlines in many blocks......way off center in the casting ! Those heads and the block were nasty but I assume the owner is wanting to keep the original's......Nice work ! I spent over 10 years doing engine work and I'd be happy if I still was.......never had as much good equipment as you do but we got by.......I'm very interested in the tractor engine story. That sure is/was a difficult one to diagnose and fix with confidence.

I do like the tip of cutting the tops off before you drive them out, that's a good idea, don't know why I never thought of that lol. BTW how you guys like the Serdi 4.0? I'm actually looking at one I may buy. I'm still using a PH2000 for guides and hard seats, roughing in with the 3D system and Serdi cutters and finish grinding the seats (Standard steel fixed pilots are just not all that accurate on my 3D system). I'm tired of cast iron dust up my nose! 🤣🤣 Awesome video, and good looking work guys!
