318 mystery problem, somewhat solved!

Re-timed it. Some how when I put the timing tape on I did it wrong and I made a mark on the timing cover were TDC is as it appeared the balancer had slipped but if you used the mark on the timing cover the engine really likes that. Idles so nice now and runs much much better. Yet to see about mileage but I believe I can now tune the EFI better now that this is set correctly and so retarded in timing.
