where is it gonn abe?
btw kev, with 99+ heads (which Im assuming you have) you can make roughly 365 horses with the comp 274 grind, you will definately need springs, I'm kind of weary of comps products since I had my motor blow due to comp lifters... but the cam grind will make you good power, along with a set of springs. you may also need a bit of compression, dyno tune, proper valve grind, t-body etc.
ok, so the low compression motor that mm&ff mag. tested had ported PI heads, 1-3/4 headers, accufab 70mm t-body, msd coil packs, and an elec water pump had 365hp @ 5900, and 368lb @ 4700. your stock compression will make up for the lack of porting. so you could expect this power range after you get the bolt on's that would compliment this cam. I'm a sucker for duration, it's what makes the mustang idle liek a real car. NE ways, if you want a hand on the install, i can help and I know a guy that is a repeat record holder for the NHRA that does valve jobs, port/polish, compression hikes, etc.
btw the high compression motor made 401hp @ 6100 and 389lb @ 4900
