"A good stock cam will run 10s with heads and a turbo, so something isnt perfect and you need to find it."

Could the "non-perfect" thing be the fact that I'm buzzing along at 5100-5600 rpm down the whole track length...with a powerband that is probably best at 4500 +/- rpm??

Stock cam, never even pulled from the block, has only 40k miles with no springs heavier than CC 980's and stock lifters in the same holes. I really doubt that I have a flat lobe.

Agreed I can do better on the 60' and I've added an Eaton posi with Moser axles since the 11.30 because I saw that the drivers side tire quite turning during the burnout. Even so, the 0-60mph on DS was 3.18 sec...not too shabby.

Appreciate all the help and advice...I'm leaning towards a tighter converter. Would like to lock up but don't think a single disc will do it...and don't want the rattle of multi-discs.

If you read on alot of older posts..... there are people wiping cam lobes today that have never changed their valve springs.... still on the stock cam. It is a fact these motors are prone to wipe lobes with todays oils. IMHO.... one can never rule this out.... no matter how unlikely you might think the possibility is....

Easiest way to check for flat lobe = remove valve covers, bar over engine, and measure rocker arm travel ???

I read your last post, yes easiest way would be to remove drivers side and check #3 and #5 exhaust lobes, normally when they go, there is nothing left and the rocker arms barely move

Get a good convertor that doesnt lose much power, you can contact Dusty Bradford for a nice non lockup that should put the power down, if your not too worried about MPH, then the real art car 16930 does fairly well too.
