The Chev TH350 I have should be good. I think we'll throw a shift kit in so my son gets that experience. Plus I like the firmer shift and I guess we'll find out how he feels about it. But I'll keep in mind you have a reference because I don't have a transmission go-to. Usually I'm buying a used one that seems good.
There isn't a tach in the car, not even a cheesy previous owner installed one like I typically end up with. So I don't have any idea what the gearing might be based on rpm/speed. I didn't think to spin the wheels and count the pinion rotation when we were doing the exhaust and we had the rear end on jack stands.
There doesn't seem to be anything sporty about this car; I'm sure it was a family cruiser with 2bbl carb, 4 doors, and AC. So probably the 2.56 gears. Which is still impressive with the acceleration the car has despite the bad trans and boggy carb. Can't wait to see how it does with 4 bbl carb, better trans, and modern ignition.
While doing the exhaust work, I had the front of the car elevated and a LOT of oil leaked out the back of the motor, enough to fill an 8oz can over 24 hours. It doesn't leak like that from normal driving around.
Wouldn't that tend to indicate the pan gasket is bad?

Crank seal would be my guess.
Either way I figure if we're dropping the pan we should do the rear main too.
Interestingly, he Buick 350 pan is flat all the way around, no dips at the ends like a chevy.

what a cool project for you and Jr.Mrk5 . Love the style of that car. The factory dents look great! Until i have kids of my own ill live vicariously through all you hot rod dads.
Yes it is flat, get a sneaky Pete tool. the Buick has a rope seal. Buick V8 oil leak kit 2 valve cover gaskets, oil pan and rear main. I loved doing those at the Buick agency I worked for. Customer pay was 5 hours, do a good quality job in 3.
You'll also need RTV to seal the edges of the main cap.
Good luck take picture

What is the max overbore On these blocks? Im guessing not much if they are a lightweight casting.
The Buick 350 is about 125 pounds lighter than a Chevy. I was wondering where the weight savings come from so thinner cylinder walls would make sense.
From some quick searching it sounds like you might get away with .060, but the block should really be sonic checked to be safe.

If you were going to do machine work, why not start with a 455?

My guess is, it's what the car already has.
Yes, but if you are going to remove it, and rebuild it, why not just start building a 455 now, and just swap them?

Because teenager?
And before you get that built 455 in it, stock up on used rear tires to swap on.
No plans to do anything major with the engine at this point. Just reseal the bottom end and add a 4 barrel intake.
I really just want to get it running reliably so he can drive it. Then if he really falls in love with it and wants to do motor swaps and that stuff we will. But I want it to be something HE wants to do.

He'll need to do that, with the 350!
Got the shift kit installed in the Chevy TH350 I've had from a C10 part out. Only difficulty was getting the pan off. I told Patrick this is what you call an a$$hole amount of RTV.
Makes me wonder if there's a sealing issue or someone is just over zealous.

Uneducated rtv user. If you don't see big gouging in case, and pan isn't bent, you should be good
You don’t put a 1/2” bead when you do RTV?
I rarely use rtv. If I can avoid it I do.
