Olds 455 Still bogging/stalling in gear?
I got my olds 455 up and running, and for a while, man was it awesome, but recently, i've had a major problem The car is bogging out, lugging, at around 2500-2900 rpm, but only in gear. I figured it was a fuel problem, so i installed a new summit mech. pump, and also cleaned up my edelbrock 750 (Rebuild kit, new accelerator pump, filters, floats, etc). Seems to run real well sometimes, and real bad others. It happens more often in hot weather. I thought the fuel bowls were running dry, or boiling fuel, but all my fiddling, and seems level was ok. My question is does this sound like a fuel problem? or more like a timing or tranny problem? In neutral, with no load, it revs great. Thats whats leaning me towards tranny. Thanks again so much,
455 Olds

Just a guess, but it sounds like it's not advancing. The timing should be fully advanced right around where you say it's bogging, the only other things are clogged exhaust, and I assume you have a larger fuel filter on it.
