Gas boiling
Also consider installing a "vapor return" system. I did this on my 67 Dart, and it helped a lot. First car I ever saw with one was my '70 440 sixpack RR. On my Dart, I brazed a tube into the front face of the tank, after flooding it with CO2 from my MIG welder bottle. Run a 1/4" tube up front, and plumb in a Wix 33040 (5/16) or 33041 (3/8) fuel filter. These filters have a built in 1/4" return line with an orifice built into the filter
You can mount them vertically or horizontally, just so the 1/4" return is on top
