I used to have 2" hooker fenderwell headers on the car, but than tied the cage to the front frame and the fenderwells wouldn't work so I put on the 1 3/4" TTI I had (At the time I thought they were 1 7/8 so didn't think much of it, but Looking back I should have made the bars tie to the frame so it wouldn't affect the headers, but hind site is 20/20.) I kept the hookers and as a winter project I'm modifying them to fit. Only have to redo tube #7 and #8. Was also going to swap in a .590 cam I have, but don't feel like doing that much work. I'll wait until I freshen up the motor to do that. I'm curious what the headers alone will help pick it up.
