360 vs 383

Also - if I have the choice between a 383 and a 400 block, I'm going to build the 400. Whoever built the first 400 stroker basically rendered the 383 useless. The larger bore of the 400 is a significant advantage when built to whatever the intended degree. Beyond a faithful factory-style restoration using original, numbers matching parts, there is no logical reason to use a 383 if a 400 is available for similar money. I currently have 3-4 400 standard blocks myself so I'll never have an issue with that.

Plus, externally the 383 and 400 are the same. Put a 383 Magnum pie tin on top and no one will know you have a 512" low deck. Same thing with a 408-440" small block. See the F.A.S.T. class for proof of that.

The 438" that I built and linked to was for a friend. He was DEAD SET on using a 383. It took a lot of convincing to go the srtoker route but in the end, it would have been more money to refurbish all the stock parts - trust me on this, I priced it all out to the last penny. And unless he put a big cam in it, he was not going to have as much power as the mild stroker provided.
