wrightway, i've got a '65 Nova. Last year with a 477 BBC i was running 9.7's-9.8's in the heat. Right now i'm putting together a 540 hoping to run 9.0's at 2850 lbs. Shouldn't be a problem a buddy of mine with the same engine built by the same shop same specs is running 9.2's at 3400 lbs. Time will tell.
