Maybe at this point some dyno time might be a good investment.????

Is that supposed to be "MSD box"?

What did you find wrong with the motor. When I talked to you in San Antonio, you said the leak down and the compression test didn't look good.

I had a problem like that years ago when I had my chevy ll after weeks of tearing my hair out turned out to be a bad msd box. It didnt miss breakup just no power going down the track.

A really bad ground? New MSD box incorrectly wired on installation? Can you borrow another box after you check your grounds and installation?

Replace pickup with a known good one. better yet put new one on.

Same here car lost 3 tenths in three passes. Changed everything but the windshield before finding problem with MSD.

Pat at Techwest suggest I put a 10 gauge wire on the positive and negative post of the battery and run them directly to the msd box. Sooo I will do that and see what happens. Ed Wright offered to let me borrow his spare 7AL3. I will take him up on his offer and have it with me also. If no go then as Scott suggested we will dyno the engine and find out if it's the engine or the car. I can get it dynoed anytime I want for free so at this point im wishing I would have already done that. Thanks.
