Hey guys, some of you know I have been looking for some aluminum heads for a while. I have a set of Gt40 heads (FMS-M-6049-X303) that I can get my hands on for $550.00 or best offer. After looking these up
FMS it looks like they might be perfect for my set-up. They are suppose to only have 6,000 miles on them.
Right now, I just have e7's that are nicely home ported. I am not looking for a drag car here, but I am looking for a nice gain in horsepower and weight reduction. With the performance numbers on these heads, would I be stupid to pass this deal up or should I just pay a little extra cash and get some trick flow or edelbrocks?
Keep in mind, my 5.0 is a fresh block and is going to be in there for a while. So buying a head to match a future combination is not an issue right now.
One thing that is holding me back, is the chambers on these are suppose to be 64 cc, and I assume that is gonna lower my compression a little compared to my e7's.
The goal for this car with the current engine, is to get it to run low 13's to high 12's. I have no idea how close I am right now, cause it rained when I was planning on running it.
