Headers For A Chevelle

[GM-26]

I am thinking about changing the headers on my 1972 Chevelle. The car has a LS-6 454 motor. I currently have Hooker Super Competition 2" tubes with 3 1/2" collectors. I'm looking to see if anyone, on the Board, has installed the 2 1/8" style on a 1968 to 1972 Chevelle. Those have the "over the frame" tube. Just wondering if you have to cut the fenderwells or if they clear everything. If cutting is involved, then they are not for me. My buddies are telling me to put cast iron manifolds on.

Yes you have to notch out the inner fender wells. I have a set if you want to buy a used set.

Nick, Other than looks I don't know if the bigger tubes would be any advantage to you. Maybe on a heavely modified motor. Super Comps are good Headers. JMO Sam

I like the appearance of ceramic 2 1/8" tubes. You're right, there's probably no performance advantage for my stock "LS-6". The best thing is to replace them with the same type.

what is your goal for the car? mike

I originally was looking to use the bigger tube headers for the aggressive look that they have and if I can get a few more horses out of the motor. Considering the combination that I have, I will stay with the 2" ones.
