I have for the most part played around with the old reliable small block chevy, but if I had my want list I still like the 283 for being able to get old school horsepower out of it. I had a few that would turn 7 grand with no problem. And of course let's not forget the 302 engine from the 69 z 28 camaro.( boooYeah) that thing would run right out of the box. wish I had one or two.
