My builder used a QUICK FUEL 850 BRAWLER with Edelbrock Victor intake but that was too much intake and after talking to Butler I switched it out with a Performer RPM. It runs a lot better on the streets now. I'm also running Doug's headers and a flowmaster exhaust.
The car has never been on a dyno. I've had it since I was a teen and when I started making adult money I had a friend of a friend with a machine shop do the engine work. He is a great machinist but terrible at finish work so I kind of ended up with a basket case.

How do you like the Doug's headers? I've got a bad leak on one of my manifold gaskets so i'm planning to buy some new headers but want to be able to justify if the price is worth it over a set of ceramic coated long tubes from summit.
