I'm looking into buying a rebuild kits for a 4 blt main 350 from a 79-80 chevy truck.

Most kits give u different options and im just trying to better understand these options. Fredo? maybe you can help me understand.

1. Pistons - Dish or flat top? What are the pros/cons of each one?

2. Bearing sizes - STD, .010, .030, etc. I'm guessing that if you bore out your cylinders .030, you need .030 bearings?

3. cams - i don't understand lifts and durations and things like that...what do they mean and what should i be aiming for? I'm guessing im looking for something that will give me the most torque 1000rpm-35000rpms? If i get a 'big' cam, will that affect my ability to produce a good strong idle and affect my throttle response from idle?

4 boring out or not - Pro's cons of each? When do you decide to bore and not to? when the wall is scarred? will a 355 make more power?

I'm also planning on adding TBI onto this engine sometime. Is there any problem running TBI on something that is not a bone stock 350? I bought a couple of books on amazon already, just waiting for them to come in. Besides that, i've been reading on hotrodder.com and most of em seem to recommend these 2 kits.
