Rebuilding an engine: Where to start?

Lets say instead of getting a whole new motor, I rebuild an old one. Chances are its gonna be a chevy 350 from the 1969-1980 era. It's a big gap I know, but I'm not looking for any certain model. I've been looking at some 1980-1984 El caminos, and some 70s, early eighties corvettes. There cheap because the engines never came with alot of horses as we all know. I'm gonna need some stuff for it, i dont know where to start. I want it to meet the specifications that i desire (great performance, driveability). Please give me all the suggestions you can, starting from part to part and how it helped the total performance of your car. Thanks a million.

If I were going to build a SBC this is what I would do.

Spend some time at the biggest swap meet in your area. Chances are you will be able to pick up a good 4 bolt main 350 block for a very reasonable price. Rods, and crank aren't hard to find either. As for heads, definitely go for the pre-1980 thick wall castings. The thin wall castings tend to crack around the exhaust valve pockets and for my money are pretty much worthless. The rest is simply machine work. All other parts are aftermarket to suit your requirements.

Another option would be a junk yard engine but until you have it torn down you don't really know where you stand with one of those. Could be really good or a piece of crap.

The best thing about SBCs and the reason most people go with them is parts availability. There's a zillion of them out there and you can find parts everywhere. The drawback is that you become just one of the crowd, but there's nothing wrong with that.

Good price is a relative term. Good price to me would be under $200 but only if it were disassembled and cleaned. A good price to you might be half that.

The advantage of buying at a swap meet is that you can pick one up that is disassembled and you can check it over, measure the bore etc. and pretty much know what your're getting. With a junk yard motor, you don't know till you get it home and tear it apart what kind of condition its in. Junk yard motors are usually a lot cheaper for that reason.

I see what you mean. Where exactly are these kind of swap meets? Anything soon? Because the weather is getting a little colder, I should jump on this ASAP.

Blakblur,
From experience you dont NEED a 4 bolt main block. I had a built 2 bolt that I beat pretty hard, saw 8000 RPM several times(first gear only) and it held up just fine. If you can find one great, but not necessary. I believe the 350s used in the pickups were mostly 4 bolt mains, at least the ones that came with a 4bbl,along with the high performance car applications.
If you are not going to use forced induction such as blower or turbo, go with as high compression as you can that will run on pump gas to keep it streetable. Gives you more umf off the line.
A set of headers, and maybe a matching intake, carb, and camshaft set from Edelbrock, Holley, etc. to top it off depending on what you want for performance. If you are looking for off-the-line performance stay with a dual plane intake and a vacuum secondary 600-650 carb, and mild cam. Like I said, from experience.
Good luck, Skidmark
