I'm looking to get a cam set in '05 and need some help with selecting the right grind for my combo. First things first this is what I'm closing out 2004 with ...
SCT Multiprogram chip (BamaChips)
Steeda Underdrives
MAC Prochamber
Flowmaster Exhaust
3.73 gears
NOS Wet Kit
The plans for 2005 already include the following (so far) ...
Accufab Intake Plenum & 75mm TB
K&N F.I.P.K II Air Intake
FFRP Shorties
Port & Polish for the heads
24 lb injectors (maybe)
Cams (grind undecided)
Now for the fun part. I will probably end up using a shot of nitrous somewhere in the 100-150 hp range after I see how much the motor wants to take. With that being said let's get to the meat of it.
Based on the September Issue of MMFF, there are 2 grinds by Comp Cams that I have my eye on. (other recommendations are welcome) Namely the XE262AH and XE270AH grinds. The following figures are from the MMFF test motor.
XE262AH:
Lift:....... .550
Int Dur:... 226 deg
Exh Dur:.. 230 deg
Lobe Ang: 113 deg
Pk HP:..... 386 hp @ 5,800 rpm
Pk TQ:..... 383 ft-lbs @ 4,800 rpm
largest
hp gain:....50 hp
largest
tq gain:.....45 ft-lbs
XE270AH:
Lift:....... .550
Int Dur:... 234 deg
Exh Dur:.. 238 deg
Lobe Ang: 113 deg
Pk HP:..... 388 hp @ 6,000 rpm
Pk TQ:..... 383 ft-lbs @ 4,900 rpm
largest
hp gain:....57 hp
largest
tq gain:.....49 ft-lbs
Of these two which would best fit my current and upcoming mods with a 100-150 shot of juice? Or are there other grinds that I should take into consideration? Like I said, I'm open to suggestions, this is just what I've looked at so far...

Side Note.. MMFF believes that the XE262AH will be the best seller for comp cams.
turned out to be alot longer post than I thought it'd be.
