I plan on punching this little 250 and bumping up the compression ratio.............Since I am a machinist, I have thought about a little Turbo more than once. Thought the Clifford would be best suited for it when I cross that bridge. And I thought I could run it on the stock engine until I get the other block I have laying around built up but from what I see you guys are saying it won't function............So here are some more questions.......If I bought a Offy, would it preform with the 500 CFM carb on this stock engine? Are the Offy's water heated?

I put the carb back on the truck this afternoon and tried it.........Idles alot better, but still bogs when you tramp on it. If I could get that to get a tad better I could live with it.
