Hey guys,
I recently had a heads/cam kit installed on my car, and had it dyno tuned a few weeks ago. The max power was 381HP, and 363.8TQ.
The heads are 5.7 stage II from Patriot Performance, and the cam is a CC4 (forget the actual numbers) from Comp Cams.
It feels like I lost some torque down low, but it gains quite a bit over 5000 RPM.
Could someone look at my dyno sheet and tell me if it looks like it should? Maybe its my imagination, but it feels slower down low until over 3500RPM.

I'm guessing you don't have LT headers based on your sig...so, I'd be willing to bet you'd see a good 30hp gain from installing a set. Maybe that's what you're missing out on.

 

do you have the numbers for the cam? Sounds like a nice buy worth the money, especially with some LTs.

 

The numbers are Lift: .581/.581 Dur@.050: 224/224 LSA: 112 114.
I got it from LS1speed.com.
No I don't have headers yet (on the way), but the stock heads/cam pulled harder down low. This seems to pull harder up top. I just wanted to know if my dyno sheet looked consistent with what it should be putting out down low.

 

Do you guys think the dyno sheet looks normal? Is the less torque down low normal?
