they flow real close to the advertised flow #'s out of the box they flow'ed @ 28" 4.060 bore 2.05X1.60

.100 64 51
.200 118 101
.300 170 130
.400 210 158
.500 242 178
.600 260 192


I havent had them flowed after the potwork but my machinest said they flow the advertised #'s and possible a lil more now...

the portwork was preformed due to the #'s being slightly off the advertised specs, I'll get them flow'ed again before I assemble the longblock, but that wont be untill at least another week or so...

Hey 2wld4u, I loaded up the specs you listed and came up with these numbers for you combo.

615hp @ 7000RPM
520 tq @ 5500RPM

I can probably fine tune them a bit with a little more clarification of the cam specs and some other stuff if you want, but these should give you an idea.:thumbup:

hey thanks!


p.s the cam is a Lunati Roller the part # 638-50144 (jegs)

I dont have a cam card, this was the cam I was thinking of using with my combo, I could possibly get more info on the cam, ( Jegs tech guy's are really cool about that stuff) just name what youd like and ill see if I can get the specifics...

Well 2Wild4u, I went with a few assumptions on the cam to get the numbers for you.

I set the Lobe center angle at 106 (Cam Degrees) - Assumed

I set the Intake Duration at 276.0 (Crank Degrees) - From your Post

I set the Intake Centerline at 102 (Crank Degrees) - Assumed

I set the Exhaust Duration at 284 (Crank Degrees) - From your Post

Then I set the valve lifts at 640 / 642 also from your post.

This gave me IVO (BTDC) @36 / IVC (ABDC) @60
EVO @ 72 (BBDC) / EVC @ 32 (ATDC)

I figured these were pretty close to accurate, but if you can get the cam card or the specifics from Jegs, then that would work perfect.
