even if you port your heads it wont be close to how much hp you get from a box stock set of AFR 185's...

yeah, yeah, yeah. I would have put AFRs on my car if I had had the time to wait for them. However, my ship was sailing and my car had to be on it and I could not wait for the AFRs to get to my builder so he went with the Performers. It is what I got and they'll have to do. I am just curious if I cannot tweak my engine to get close to 500 hp without stroking or putting a hair dryer on it. I am in the neighborhood of 450 hp right now, which is a pretty respectable neighborhood, but the grass is always greener and I wanna move on up. To the East side. To a deee-lux apartment, in the sky.
