Stalling under load
I have a 67 327/210hp with a Powerglide. It's an RS without the high-performance rear-end upgrade, so it's a 3:08 - unless, of course, it was changed at some point in the past.
Today, I was running a few errands. It probably ended up being a round-trip of about 30 miles or so - not too bad. On the way back, however, the car began to act like it was running out of gas. It idled perfectly fine and revved fine, too. But, I put it in gear (high or low didn't matter) and after brief acceleration it would be starved of fuel.
A couple things are different about today than any other day:
1) It has been HOT here lately, and today is a bit cooler - it's 93° outside right now.
2) I was low on fuel - not on empty, but my gauge is all screwed up and I don't know how to fix it. So, I've run out of gas before when it was at about 3/8 on the gauge. Today it was at about 7/8. Bottom line is I usually fill up every 100 miles because I just don't know how much gas I have. In any case, I filled up and it started to spill out at only 8 - 8.5 gallons...
So, my tank is full and the car sat in a parking lot for about 30 minutes or so and had a chance to cool off somewhat. It started up just fine and did not act starved of fuel for the final 1-mile trip back to the office...
Any ideas? I'm really bummed out because I have no clue.
By the way, I did have my dwell meter with me and while I was stopped on the side of the road, I hooked it up. Dwell is steady at about 30-31.
