[RACER X #99]

Venom, If you install that Pro Stock BB in you Cobra you will be the Baddest guy at any car show and cruise night. But when you take it to the track (not dragstrip) every sb will piss all over your car. Those huge valves are meant for high rpm power and you don't want to wind up like the Boss 429 Mustangs, Killers at the strip but pigs on the road.
