Even if you don't use a roller cam(not needed for just 350-400 HP), there isn't much of this stuff out there that is used like flat tappet cams, so that leaves you with having to buy a lot of these parts new, and it just isn't cheap like SBC stuff is. Roller rockers is another costly purchase you will need to buy, there just isn't much of this Chevy 6 stuff floating around out here that is used. An average used aluminum intake manifold is often $250+. $2K will go away very quick, just be prepared to spend more to get it completed.
Ok, then what about the 250? I was after more cubic inches, but can I pull something out of the 250 that would be impressive? How far will the $2k go? I can help with some of the cost over that. He just wants something impressive and different. Something you just don't see everyday. I have built many small blocks chevys over the years. What RPM's are these capable of?
I would think that the stroke being what it is, it could be made scream,,,,
