looking for a little info . i have a 454 chevy big block at work that runs our generator near as i can tell its from the mid 80s .has(hi-perf pass) stamped on the block i can get other numbers if i know where to look.weve had it the entire 32 years ive been there and it runs off natural gas. anyone know what type of power this thing would put out? i always thought it would be a cool project to put it in a gbody monte.Im an oldsmobile guy so probably would flip it once done. this would be on the back burner for a while with all the other crap i got going .would like to hear from you chevy guys thanks
