weather is too dam hot right now for you to expect good 60's, i bet your IAT's are way up there when you launch, which will pull timing netting shitty 60's,
on the good note, the mph sounds very promising, and i would definately do the 4.10 gear swap...

try smaller slicks Rick.. some 26s or 27s, you'll get a better launch out of them... try that, and check your pinion angle.. maybe it could be off and that also affects your 60fts.
