Great power for a na motor. Whose heads are you running and what size are the runners? 205cc or 225cc?

Killer. I bet some 1 7/8 headers and a 90mm intake and tb could get you well over 530rwhp on a little ol 408 Those must be a sweet set of heads.

The heads are APE 6.0 ltr race heads, and believe it or not they are 237cc intake runners.


Thanks for the props guys. whats cool is that this power output is actually how I will drive and race it on the street (i.e no dyno tricks).

11bravo I do plan to do the big headers and intake so I'll let you know how it goes once that stuff is on.

I got mine from Discount tire and to be honest I don't know what kind they are . They are the same ones that Todd@discounttire had on his ride.

I weighed my stock wheels vs the z06 ones. Stock chrome 10 spk z28 rims are 45 lbs with tire. Z06 replica with tire is 60lbs so there is a considerable difference although I am not sure how much this would show up on the dyno?
Every tire I bolted on I thought to my self. slower,,, slower,, slower,,, and slower.

Hows your stroker coming along?
