The engine is attached to a Tremic 5-speed.
I've got an 8 3/4 rear end with 3.55 gears in it. Only thing done to the chassis besides this rear end swap is: Beefed up rear springs, installed gas shocks, added traction bars, a front sway bar and upgraded front power discs

I really appreciates the input from you all. Wish l had kept up with this fish and motor, in all the years I've had it.
Mind 'ya, The purpose of my car is mostly sentimental everyday driving tho I'd like to get on it from time to time and take it to the track in spring/ summer. I'll dig up my build sheet over the weekend and share more of the internal build.
My initial thoughts was changing the four bbl to the 6pak for power gain but also for the big fashion statement. Tho it is a great expense, if the power output increase can be obtained with a 750cfm and 1 3/4 headers, opening the passages of the fuel/exhaust flow, then that surely would cost less than the anticipated $2800.00 6pak setup with a much better gain.
Rumblefish: Are the tti headers you've mentioned with 1 3/4 pipes full length headers or shortys? Does it allow for easy access of removal of spark plugs? My full length headers hang to low and are easily scraped. I am definitely game on changing my headers out. If the tti brand is full length, do they tuck in nicely under the car? Or do short tube headers perform just as well. And what about the intake manifold? I bought an old summit racing dual plane intake.Are there better dual plane intakes around? I once had an Eldelbrock LD340, I noticed a good gain with that one over the stock intake back in the day when I had the stock carter afb carb on it. So far, I am hearing a 750cfm double pumper and 1 3/4" tti header pipes.
