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.

how about a blower swap?

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

blue03mach1 what is your horsepower goal? Is your car a daily driver?

 

[blue03mach1]

um im not sure what to make my daily driver. my mach1 just hit 27k and the roush has like 3k miles. whatever the car makes with those mods im happy. so around 450whp? if its around 450whp, im going to have the tuner detune the car down to like 420whpish. Right now the mach1 is my daily driver.

 

[blue03mach1]

yeah i think i might switch to a bigger intercooler
