I just didn't know if that particular 650cfm double pumper was available before Holley started putting in the check valves.
At any rate, I still don't have much information to try and figure out why this truck is pig rich and lighting up through the exhaust.
Do you have an angle that might explain his problem?
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.
