Dirk,

Thanks for the offer to help. I've got family in LaCrosse - beautiful area. Ground wires are my current focus. I'll be changing some things around even if it doesn't prove to be my problem.

Nitroman,




I plan to eliminate the vehicle wiring from the equation one way or another in the testing process. I think I'll start with what Alan suggested and run all MSD wiring straight to the battery to eliminate the rest of the vehicle wiring from the equation. If that doesn't do it, the next step is an HEI to eliminate the ignition as well. The second MSD box that I tried was brand new, and will be in retested in another vehicle this weekend or next, so that will confirm whether or not that box is good.

-Ben

have you tried a different carb?

Ben,
I built a new engine for a customer and it missed and popped from the very first time we started it. Took it out of the car and put it on the dyno and all was fine. Changed everything in the car we could think of. The last thing we changed was the master cut off switch. We should have changed it first.

Now that you mention it, I've heard of that happening before.
