We have been running our 496 predator headed engine for over 5 years very little problems in a 2850# car with driver 7.68 at 178 with a 727 coming out in 2nd. gear. This year we up graded to a RJ car with Andy McCoy duster pro-mod body same engine combo 2240# with driver and a glide. Going testing in 2 weeks.
I'm hoping to get my car in the mid 7's so I can run A/Gas 7.60 index
596 Predator/Glide and the car should be 2450lbs on the starting line.
