Small block bottom build horsepower limit

Well…..he sold that motor to a guy out West. Guys name is Steve Wasinger(sp)?
He started racing it last season, still racing it this year. Guess the guy was just in a final round with it very recently. Jack told me it’s on YouTube.
Races it I think at some track air/ altitude is typically 6000 feet. Motor is in a Duster, runs 6.40’s

Edit..looks like he is president of a drag racing club in Northern Nevada
About-Us

I would need more info. Weight, state, track, how many times a year, etc. some people call themselves a racer but only race 2-3 times a year. Many go to two day races and only race one day. There are racers then there are racers.
