Hey guys, so my 71' GMC wants to bog down under full throttle. It'll accelerate to about 45 then will just stay there but if you let off the gas it then has no problem going on to 70+ and runs great otherwise. Any ideas on what could be causing this? The 350 was just rebuilt and it has a new q jet and hei distributer along with new everything on the outside of the engine. Thanks in advance.
