2 more things no one's mentioned about doing the 383 conversion, the 400 crank will not fit into a 350 block as is. The main journals need to be turned down to the 350 size. Also, you will have to use a 400 flywheel/flexplate due to the external balance. There was also a mention of using a blower or nitrous or even both, not with aa stock 400 crank. It won't hold up. The 400 crank is cast, not forged. You'll want to run a forged crank wiht either a blower or nitrous, along with a 4 bolt main block, forged pistons, and forged rods. Running cast parts,...can you say "Grenade"?
And one more thing, most of those imports are all show, no go. I've driven many of the so called "hot imports", so far, not impressed. Had a guy in a while back with a turbo charged Honda, supposedly the fastest import in town. It could barely pull itself along. There have been exeptions, I have driven a Supra that would do an honest 160+, and some of the Nissan 300Z and Mazda RX7s are pretty hot, but for the most part, it's all bluff.
