Carb. Main Body

Any body seen or used these upgrades? Summit sells then with a claim of 25-50 extra horses. They are basically re-worked main bodies minus all the choke controls. I am considering one on my 4150 dp. If you have done the upgrade let me know....good and bad.

depends on the size motor and carb size you have now. 390 with a 650 holley will definitly benefit from a proform 750 main body.

if your froggy you can chop the tower off your holley, and use a dremel to blend eveything. you'll end up with a similar gain and you will have saved some $$$$
