We Inliners even have a car cub. Go to inliners.org on the web, it's interesting. My 292 Chev. 6 cyl puts out about 350 H.P. and will do a number on almost every street driven V thing There's a book by one of our members about hopping up the 6 cyl engine. They can make up to 700 H.P. in radical form turbocharged can make more with nitrous, etc.
