Engine Woes

Well, the 347 stroker was never designed to last for more than 5k miles. Only recently have parts (rings/pistons) been redesigned for it that give it a chance at reaching 50k miles safely. Adding boost to an engine that has been maxxed out as much as the 347 has is just asking for trouble. For a race-only car, go for it. But, for a daily driver, I wouldn't. No way. I'm not even real comfortable with the idea of adding boost to a 331 stroker, let alone a 347. As long as the parts used were top of the line, a 331 would be okay with a max of 8-10 pounds of boost (10-12 if intercooled). Still, you're jeopardizing your ride with alot of boost. A stroked engine adds alot more load on the main journals all by itself. A boosted stroked engine adds ALOT more load. The 302 block isn't really that strong to begin with.

If you've got the money to build it right, and that's what you want, go for it. For me, I could get equal performance with better reliability for the same money elsewhere, but that's just me.

Take care,
