Default Re: 81 Gas Marathon barely runs pops/backfires

Forget the motor mounts; I convinced myself they were correct the way they came off.
I put the motor in and got it running....it took a while to get it to fire off. I didn't make it around the yard before it started acting up. I think I'll do the HEI swap this week.

The rebuild was still worth it; the crank bearings were shot and I have a lot more compression. The short period it ran had considerably more power.
