Yup. Runs pretty good at idle but the timing light shows 40*. I put a timing tape on the balancer and made sure the balancer hadn't slipped before I put the tape on.

I'm telling ya, you're 180 off on the dist.!! just because you can, take the distributor out, spin the shaft 180 degrees and put it back in
