406 sbc vs 383.

The 383 does have a ton of tq, and doesn't need to rev to hit good HP numbers. I believe that since you don't plan on driving this a lot, that you should consider the 454. More money without question, but you get what you pay for. The difference between the two is very noticable, the 454 will always have more low end.The intake has a shelf overhang that covers the area above the oil pressure port on the back of the block.

Both of the above replies are correct, since both the 350 and the 400 are on the same archetecture, once you take a 350 and put a 400 crank in it, it is just a bore difference form being a 400.
