How do I make him understand?

Im not disagreeing with what you are implying or the results you have accomplished, what im saying is that with two cars mildly modified (mid 12's - mid 13's), one a AOD with good converter and shift kit, non-lockup, plenty of gear, shift improvements and the other a 5 speed with a good driver, the 5 speed will win, no problem.

You cant compare your professionally built, top of the line, race Lentech to what Im talking about, and I dont see how anyone can disagree with the example Ive laid out, as its what happens in the real world.

What im really surprised to hear is that going lock-up netted you 34 more HP over non-lockup! Thats quite an improvement, and apparently reflects in the success you are having with your combination.

Most tranny places recommend going non-lockup to retain the torque multiplication, but I guess they are giving poor advice if lock ups run that much better. Are you locking up in third and going through the traps in third?
