Q-Jet to Holley carb swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

C-ries · 05-15-2018, 04:52 PM

Hi everyone,
I have a 1971 GMC C15 with the stock 350 engine and TH350 transmission. I am working on swapping from the stock Q-jet carburetor to a Holley 4150. The problem I'm stumped with is getting the throttle cable hooked up properly. When I hook up the cable to the bracket on the new carb the foot pedal will only open the throttle to about half throttle when the pedal is on the floor. Anyone tackle a swap like this or know of any sites/pictures of it being done?
