Double-pumper racecar Holleys are problematic on the street unless you are a carb expert. I've played with them for years and finally bought a tuner-reworked Holley 700 DP. The carb guy said there were 35(!) different areas modified in my brand-new carb to set it up for a 351-C in a street Pantera! FWIW, it increased power and torque across the board and returned 21 mpg on a 1000-mile open road run. So I suggest you take Ron up on his offer. Or get used to the smell of gas on your hands at supper.
