The x-ellerator, unless they changed it, was a 2 piece deal that came with a Holley adapter. Both a 2 barrel and Q-jet carb pads were listed separately. I made my own Q-jet plate, but never could get enough pump shot to overcome the lean hesitation. It MAY have been able to work with a girly cam, tho'. I used the Team G for several years on the street with a pump gas 650 double pumper. That combo ran 13.6's. When I bumped the compression to ~12:1 and converted to alcohol, the same intake, cam, and heads ran 12.7's. All at 3250lbs. If I recall correctly,the p/n's were 7541 and 7542. Ken, you just bought some stuff from me. If you want any help with your combo, let me know.
