I'm running a combo almost identical to yours. Not sure what it makes on a good dyno, but I'm thinking around 450 rwhp based on how it runs

Thanks for the encouragement, but i would say it is official i've out grown these heads, it was a budget build but, to be positive at least i have a good base to grow on , i know i will have it apart soon i do every year.lol

Did you ever get yours to the track HCI2000SS?

What makes you say you've out grown the heads? No doubt they are not the best head for the application, but they should do pretty good.

Never made it to the track yet with the new tune and Fast intake, or the with the nitrous either, but I need to

Is it a T56 car? If so, then yeah I think the numbers are low also. My buddy dyno'd 430whp N/A and 570whp on a 125 shot on a SBE LS1. And that was thru a th400 and 9"

That cam is wierd. Nitrous spec cam and you gained ~150hp on a 200 shot? Lol

M1SERY

Yea I'm taking it to track Saturday to find out , other 5.7 with a NA cam gain 20mph on a 200 shot, I will keep posting results

M1SERY

Update : got to the track, weather has been horrible we had to break between sprinkles , the test results got me thinking bout my cam decision , may change it out to a NA cam, here it is
Just for comparison I will list my old set up car weighs 3890 with me in it

Old setup 346 ls1, prc stage 2.5 5.3 heads, ls6 intake, 239/242 111, na 114 mph @ 12.1, 200 shot 134mph @10.5

New 370 lq9 , prc stage 2.5 5.3 heads, fast 92/92, 236/250 114,
Na 117 mph @ 11.8, 200 shot 134.5 mph@ 10.47

It was painful to post the results, I now know why so many post never put in there track results , hopefully this will help others, that may be building something similar , forsake of argument this cam is designed for nitrous above a 200 shot , I will keep posting results as I go up in shot size, alway a work in progress

do not be upset !!!!

just ask brian tooley and he will guide you through.


quick note : your headers is not nitrous friendly and i believe it is holding your engine back

good luck

The 3 mph difference n/a that you got is about what I'd expect based on the difference in mods. The right cam would definitely help
