I am running a 305 in the roadster pickup.----mainly because I bought the whole damn car for $200 when I was looking for a Chev V8 to build the roadster pickup around. I really, really, wish I had a ton more horsepower. That old engine runs sweet, never gives me a moments problem in 3 years of regular useage, but Jeez, sometimes I miss that "boil the hides, gut wrenching, throw me back in the seat" acceleration that I've only previously found in a built 327 or 350.---Brian
