Quote: My GTX runs hot as well but I didn't use my airgrabber hood and run a 2" spacer.
I am waiting for my new distributer from Don at FBO and I hope that helps. Don thiought it would but obviously it didn't help you.
I just installed a high flow thermastat and that helped a lot. I also moved my fuel line from the stock route to a braided line from the feed to the fender and down to get it away from the block.
I think adding another fuel pump is just masking the problem, a new thermastat is like 10
I'm quoting myself
For the record I got my distributer from Don at FBO 16 initial 35 total, set the timing and then sit the idle mixture and my car now runs at 180 even while running in the garage at 3200 RPM to check full advance, went for a drive and pulled back in the garage and its running at 180. I'm returning the radiator I bought.
I'd take a hard look at your timing. Are you running vaccum advance to help it idle?
