The motor is a 436 on a 325 shot of nos and runs 5.40s at 130mph at 3100lbs. The promblem is you have to run a factory valve angle head in the class he runs and was told by a TEA { i think it was them } he would pick up about 70 hp. I never beleive what i am told by sales people so i thought i could get some good answers here.
