i run 193 heads on my stock car small block 350 4 bolt main, with 480/480 hyrd cam. 1.94/1.60 vales .40 over K.B. flat top pistons ,vortec rods. tourqer 2 intake and headers ,84 camaro steel fly wheel , 650 double pumper holly, 5.5 lbs balancer . on 1/3 mile high bank track. the car comes of the corner really good but the end of the straight away it stops pulling about 5800 rpm. . but corners is were you wins races. this year i am putting 2.02 1.60 vales with 507/507 lift 247/247 solid cam, with 1lb balancer engine will be fully balance. to see if the top end will come around. Will this help?
