I was forced into my first build(my current engine). The best advice i can give you is, do not guess and do not take chances. Also, understanding the inner workings of the engine is a good friend. Look up some diagrams of the engine and find flash pictures of how it works. If you underdtand how it works, you will understand how to build it. I would aeperate all of your bolts into seperate bags. I put my stuff in labeled ziploc bags(intake bolts, valve cover bolts, head bolts, bellhousing bolts, etc.). And dont throw anything out until you have replaced and installed it. You never know how hard it could be to find something you need, and you dont want to kick yourself in the crotch for throwing it out. And if you have ANY questions or doubts, ask the forum. You can even contact me directly and i can help you the best i can. i was thrown into my engine build at 16 because my dad was too lazy to help me. I had a spun bearing. So i disassembled and rebuilt my engine on my own. Good luck! Its honestly not as hard as you probably anticipate.

That'll be a 388. I know a few people with them.

check the batteries in your calculator.  a .060 bore on a 350 won't jump up to that high of a displacement.

Del, i wasnt saying it would on a 350. A .060 bore on a 350 would be a 360, but a .060 bore on a 350 with a 3.75 stroke (400sb) crank would be a 388, considering a 383 is a 350 bored .030 over with a 3.75 crank. For every .030 over on a 350 is 5 CI. So, i was infact correct previous statement.

ah, yes. i was looking at the fact it was a 350 block.  You are indeed correct. coupled w/ a 400 crank, the displacement w/ .030 bored 350 block would be a 383 --which sits under my hood.
