Cool! So I have a 350 4 bolt main block. It has flat top pistons in it. .060" stamped on them. Now, having said that, let me add some more flavor to the conversation. With the block, I also got a Comp Cams 268H cam, new still in the box. I have a GM tuned port intake setup. I'd like to use it, with the 268H cam. Nice thing about the TPI set up is, I can change runners, injectors, throttle body, and the tune (chip) to suit my needs. I also have my MSD 6AL box, blaster 2 coil, and Pro-Billet dizzy. Also, I haven't decided on a set of heads yet. I would like to go with aluminum heads. 2.02/1.60 valves, 64cc or so chambers. But these intake runner sizes confuse me. Looks like I should be less than 200cc? I have a 700R4 trans, 275/60R15 tires. I'm not sure about my gear ratio. But this is all for a 80 short wide truck. Use will be daily driver, back and forth to work, knocking around town. So I ask, does the cam seem like too much? What heads would you suggest? This is build the engine, part Deux. Part one was a fail. #1 cylinder is near death, engine is making rattling, angry noises. Old, worn-out 69 307 block was a bad idea to build. I had no idea it was that worn-out.
