400 stroker rookie

I will hold all future comments, my stuff didn`t work.
Went to the dragstrip last weekend, first time on track in 10 yrs., driving sucked, car had no front end lift w/ a magnum force front end, tires way too small, bad combination.
Even backfired thru the throttle body once !
Sorry to hear that. Any idea what happened ? As far as the cam that I'm looking at, just looking . Haven't called any cam guys yet just kinda tossing it out there
