Thanks for giving me your time and experience. Should have mentioned it, I have a 68 GTO. As for purpose it’s a weekend driver. I’m stationed at Edwards, AFB CA…two hours from nearly anywhere. At some point I would like to change the rear gears to 3:36 as suggested by Eric. For now I will mess with the timing and pickup a new torque converter. The wife real like the sound of the exhaust as is, I would not mind a little more rumble. I can’t change the pipes, I’m pretty sure my financial advisor would discourage against. With 2” pipes before the mufflers and 2ΒΌ” after would a muffler change be worth it? I think a torque converter is first on my list, any suggestions? Something inline with 3:36 gears and a mild budget. Any comments on the low vacuum, the manufacture said the cam should have good vacuum. I had the original carb and manifold at first and it was the same…10in HG at idle. Anyone recommend a better cam for this engine, just a thought. Again Thanks for the help.
