i have a 468 big block chevy in a drag car,it has 12.5 comp,solid roller all the regular stuff.i am currently running a 1095 king demon and the car runs low 6.30 ,i am thinking about having the guys at pro systems build me a dominator.do you think it will improve performance?
Depends on how well your Demon's tuneup matches your engine. I would spend the money on an O2 system, tune what you have. Unless the metering is way off any gains will be minimal.
