Timing Question
I'm a do-it-yourselfer with "learn as you go" skills so bear with me.
The other day I fired my '89 and it fired fine, (this was after re-gasketing my intake) even set the timing perfect. Problem is, the distro cap was spun so much that the wires were too tight. So we pulled the distro and re-dropped it. But this time, instead of setting the #1 at TDC, we lined it up at 6 degrees before and dropped the distro again. Hooked everything up and after checking the timing, she idles at 1900 to 2000 rpms. Any thoughts? Could dropping the distro with #1 already set at 6 degrees B-TDC cause this?

Yoy might have a sliped harmonic balance you should reset TDC and position rotor. To gain a little more wire slack you can spin the drive gear off the oil pump with a screew driver. after re-setting TDC #1 and rotor you can check timing mark to see if the balancer has sliped it should be around the zero mark on the timing tab
