Same here except for helping your brother with his Nova ;)
I was playing with timing and shift points. I definitely know what it doesn't like now. More timing didn't help at all. No knocking, just slowed it down.
I tried a taller set of slicks over the weekend. Didn't do a thing for me either way. Car ran the same ET and MPH with slicks that measure 30.2" as they did with tires that measured 28.5". The RPMs at the top end dropped nearly 500, yet no difference:dontknow:
