400hp out of a 351W is basically just a good intake, cam, and carb swap. You don't need to rev the thing over 5000-5500 to get that kind of power.

A 351W EFI engine is a good choice as it's already set up for a roller cam. Throw a bigger stick in it, a carbed intake and carb, non-TFI distributor, freshen the gaskets and rear main seal up, and call it a day.

I like your way of thinking. I've found that you can build a more reliable engine with reliable horsepower if you stay withing what your requirements really are. I don't need balls out horsepower for a lite little car. If I was to go nuts with power , I'd base a motor on the 428 I have laying around.
