As long as it makes pressure 140 or 25 dollars is what it is. I used an edelbrock mechanical pump because it has the largest ports. Not sure if that that really makes a diffeeence, just my OCD kicking in. It was overly expensice and too shiny looking back. I have had good luck with the newer Carter mucle car pumps sold through summit.

Great results! That thing really moves out given it's hefty foot print.

Looking forward to the results if you can get it back out this fall.
