[QUOTE="5BrothersFabrication, post: 710663, member: 2617"] Stock '85 460, idles and drives great til high RPMs, won't pull a hill for ****, sounds like it's running out of fuel. It runs like a scalded dog up til about 30-40 mph, but you just hit a point where it sounds like, the EXACT sound of running out of fuel. You can let off the pedal a little and it will run better (not great), but then you're losing speed and any momentum, and this continues until you crest the hill. Had a big Holley 4150 on it, rebuilt and reinstalled, did the same thing. Swapped it for an Edelbrock 1406 I had laying around that is damn near new, did the same thing. Several months ago I replaced the guts in the distributor, stock for stock. I'm leaning towards needs ignition recurved or fuel starvation. I think the cheapish option would be a fuel pressure gauge and run around to see how it varies. I was told just slap a Holley Red pump on it, but it's $125 and no guarantee that will fix it. On top of that, it has dual tanks and in tank pumps. Any ideas? [/QUOTE]
