I know they will help alot, but my freind still has manifolds and a ORY on his car with massively ported heads, 224/.581 cam, yank SS 3800, 4.11 gears.

track times. N/A- 2.0 60ft (street tires) 12.9 @ 107
N20-150 shot 2.0 60ft 12.2 @ 117

anyone roughly know how big of a difference headers would help? I know its lacking mph on the track times. any opinions on what it should be? or capable of?
thanks.

I'd say 20rwhp with LT's, what catback does he have?

it is a custom 3" Y-pipe No cats, and a 3" over axle w/ a dynomax race magnum.

Order 66

I bet he can gain 40hp with a good set of headers. Dont know why he doesnt have them already.

I went from ported stock manifolds no cats cutout To pacesetter LTS and true duals and a ls6 intake and gained 58rwhp

He's leaving atleast 40 rwhp on the table considering he has that cam and ported heads. Tell him to get some LTs.

When we put the car together headers wernt in the budget. When we were at the track i was wondering why it was so slow in the MPH area. I kinda figured all the head work and cam came to an abrupt stop when it hits the stock manifolds. I was just trying to get a ball park on how much it will make a difference so i can convince him to get a set.
Thanks.
