hey all,
im planning on ordering cams, cai, smaller pulley, crank pulley, heat exchanger, may be LTs and probably porting the heads and then getting the 427r tuned a BBR. Probably going with some custom comp cams. Ive seen people posting cooling issues when swapping a 2.57 pulley and a 7.5 crank pulley? They were saying the heat offsets the power gained spinning the little s/c. Has anyone heard of this or ways to prevent it?
