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?

For the heat issue will a bigger intercooler and bigger raditor help.

Did you mean you're getting it tuned at BBR?

Anyways, I don't really think the gains are going to be offset. Of course any time you spin a blower harder you're going to create more heat. Anyways, I wouldn't worry about it. I'd throw an AFCO heat exchanger on there and maybe an electric water pump and you'd have nothing to worry about.

Better add a shortblock to that... at least rear end upgrade and P-51 clutch
