We took the coil and ignition box out of the car and ran it on the Dyno made good power[/QUOTE]
Over the course of time the two things that would kill my car was a bad MSD box or a broken converter!
I had a Sprague break in my old Trans Torque converter , that I sent to Mike Munsinger at the time and he said the converter was good - put it in the car - still slow.
I finally sent the converter to Coan , they found a broken sprague , fixed it
Result - car fast again! These bloody things will really make you chase your tail.
Try a converter from a friend ,hopefully a known good piece, I think you might just find the "cure". Bill you might remember my MSD problem from Lebanon Valley a few years back, my car was slow and you said it didn't leave like it used to. We changed a bunch of stuff ( including the converter ) then last time shot on Saturday morning Glenn and I put spare MSD and coil , Result - car fast again. Engine never missed or did anything outwardly stupid just not fast.
I hope this helps, we have all been down this path!
