Dilemna: I have been procrastinating working on the pulling truck for 8 months (I know my fault), but it did not run right last season and pissed me off, so I just let it sit..... I had a Holley carb on it, and worked well for pulling, but I wanted an all purpose carb for inclines (hill climbs if I decide to do them) and daily driving. I know I probably won't win 1st place at the pulls, as I am under motored (compaired to the rest), so until I build the BBC, I wanted to have a DD that I could pull (and used to do well). When I got the 78 I really didn't need the 80 as a DD so I let it sit. Now I want to use it as a DD for the summer (better mileage with the OD), and pull with it for fun. Problem: It is running out of fuel at 3500-4000 RPM's. The carb is now a Edlebrock Q-jet. I replaced the LT1 mechanical fuel pump with a performance electric one (thinking the problem was the pump was starving the carb for fuel). That did not help, and I checked all the lines for obstructions (didn't find any). The performer manifold I have (dual pattern) allowed me to unbolt the Q-jet and bolt on a buddy's 750 double pumper set up for a built Ford (don't flame) 460 that tach's at 7200+ while pulling. Right now that carb works, but is WAY too rich. We deduced the problem was with the "new" (although it been on the motor for 14 months) Q-jet. It always had problems, but they have gotten worse. Does anyone (already tried a search), have any documentation (online or electronic) on how to tear apart, inspect, rebuild/reassemble a Q-jet and/or know what would be causing the starvation problems. The carb is supposed to be 795 CFM and setup for a 350. I have a SBC 400 that is worked over but not a monster (flat top hyperutechnic pistons, 202 angle plug heads, Crane Fireball II cam, running ~9.5:1 compression). I could see if I turned it 7000+ and it started to run out of fuel, but not under 4000. It may be something simple but I do not know my Q-jets. I can do holley's, no problem, even the Carter/Edlbrock style, but Q-jets are foreign to me..... Any help is appreciated.
