that he's using to work on.His plan is to build a high output motor but I'm not sure on a Porsche it's as easy as building a small block. Is there a good source for info to build a bigger Porsche motor?

A small block is much easier. The 928 is a split block and the crank is held in by a cradle. It's not anything that can't be done though. The biggest difference is, it is astronomically more expensive to build a high output 928 motor. To get 400hp in a 928 may cost 10x a sbc. (just a guess)
