The 01 cams run more duration then stock 03-04 Cams on the intake side so he should have gained with those. I believe they are 200 duration at 0.050. Where were the cams degreed in at? What is your intake and exhaust cam centerline?
Did you compress all the lash adjusters before sticking them back in the heads to make sure you don't have any that are collapsed or not able to bleed down(this could buggar valve seal and lead to less power). I have found 3 collapsed lifters on my brothers engine already and 2 that won't bleed down. I still have 10-12 lash adjusters to go.
What are your IAT2 temps on the blower at the end of a pull. If you are stock inlet with stock manifolds you might be wise to back the boost down to keep the temps in check as you will have a good bit of heat in the combustion chamber.
Exhaust is holding it back, but not the reason for only 700 at 26psi.
How big is your air filter?
I was able to make 685rwhp/605rwtq with a 6.55" lower and 3.5" lower with pump gas and torco and 20.5* timing on a stock longblock.
The heads were pulled from a 30k mile running engine and the cams/secondary chains were not touched. IAT temps never went over 120, averaged between 100-110. Cruising the temps are below 100.
I am running a Tork Tech Inlet, SCT 2600, and a 12" Filter.
Any idea's on what the gain will be when it leans out on E85? Would advancing timing gain power with e85 or is it just more knock protection with the extra ethanol??
I have talked to 2 people now that have experience with this dyno, claiming that cars dynoed and tuned on it gained nearly 10% on a dynojet without touching the tune, I will throw it on one this summer just for shits and giggles.
