: Engine dies after 2 hrs @ 55mph
Mar 22nd, 00, 07:32 AM
Bringing my 67 conv back from RI w/the 6cyl/3spd the engine kept dying after running fine for an extended period. I think it lost spark. I didn't smell gas and was cruising at steady 55. After cooling down, it would run again for a while. If it's a problem w/ the 6cyl, no problem: I'm putting in a 350, but I'd like to run down the problem before the swap to make sure I don't have some electrical gremlin lurking in the car w/ the new motor.

i had a car that would run fine for an hour or so and it would just start quiting all the time. it was just a bad fuel pump.
aneways i dont know how the starter is position on a straight but if its alittle to close to the exhaust the solinoid could be geting to hot making the engine quit

Also could be a bad coil or condenser, maybe points are old?

I had a similar problem one time and it was the fuel pump.

Guys, thanks. To both of you that had bad fuel pumps, did the engine sputter before it died? Mine died with no sputter, which I thought would have indicated fuel starvation?

on mine it did first so i just started to shift my auto like a manual then it became so bad it just quit anytime

I would guess at the coil, Once had the same problem, It would get very hot after running for some time and the engine would die right where you didn't want it to happen, Let it cool for awhile and it would restart and run fine for a while longer.

I had a similar issue once with a 305 that I had put headers on. The motor was a 1983 model. the silinoid was close enough to the headers, once hot, it had to cool down before the motor was started again, but once started, it matterd not, I could run all day ,, but not shut off the motor.. I had to put something between the two to block the heat,, I know i spelled that word wrong..

Anyone still following this, I had spark even when the motor died, so I changed the fuel pump. Still dies. More frequently now. I think it probably has a blown head gasket (I noticed some escaping gas from behind the exhaust manifold near where in L-6's head meets the block. I'll probably run some compression tests before I swap out the motor for the 350, just to make sure I run down the problem. BTW the exhaust is on the opposite side of the starter solenoid, so I don't think that's the problem. Thanks, steve laabs

Steve, You might want to look behind that fuel pump and make sure you don't have something clogging up the fuel pickup in your gas tank. If the tank has never been dropped before you could easily have some sediment or rust floating around in your tank. What are going to do with your L-6? I'm thinking of selling the stout 230 that came with my car when I put in my 327 but wonder if there is any market for it. Possibly if I sell it with the powerglide I can get some nibbles.

Will, just put in a new tank and cleaned up the sender because I was clogging the fuel filter pretty readily. Filter's been clean since. I'm going to probably keep the 230. They're apparently pretty hard to sell, and it's worth more to me as a backup and toy to take apart and put back together than I could probably get for it. Good luck selling yours, though. Gas prices might make the 230 popular. I got close to 23 mpg's on the trip back from RI. Steve Laabs
