Default what do you think of this build?

Heres the combo and then the car the combo will go in......

2K5 LQ4, ARP rod bolts
799 heads cut down to 61.5cc
Texas speed Tsunami cam: 235/240, .654"/.609" 114 LCA
PRC extreme springs
LS1(corvette) intake, ported (FAST to come soon)
1 7/8 LT's with cut outs
42lb/hr injectors
Pullied
85mm TB
Yank SS4000
No cats, no EGR, no AIR


The car: C4 corvette, race weight 2980 lbs.

I'm thinking my compression should be between 10.5 and 11.0:1 with power around 490-510 FWHP, maybe a little more if I tune for E85 only. whats your thoughts on this combo?

I would shoot for a mid 11 second pass rather than a dyno number. LS1 intake is an LS1 intake. Doesnt matter if it came off a trans am or a vette.

he did note that a ported FAST will be on the way.

but i still think just milling the 799's isn't enough to match that cam.

Well, the reason I said that is because of the way he stated it. I was just letting him know that it is not any better since it came off a vette.
