Just went to the track tonight for the first time in about 5 months. Last time I ran on street tires and had trouble hooking up, I had a 2.2 60ft and ran a 13.72 just after my header install. I put in an Art Carr Tranny and a torque convertor made by a local convertor shop "2800 stall, only stalls at 2000, even with ET streets". Also I put on my 1.6rr's for this time out. I got a 1.955 60ft and a 13.738 1/4 on ET streets. Kinda dissapointed since my last time without the rockers and stall was slightly lower. The ET's are a little taller than my street tires so I wonder if that made a difference. Anyway, I figure thats not too bad for 150,000 miles on the clock. It doesnt seem to have much compression anymore as it has lost much of its low end pep. How does this sound for so many miles and my mods, about right or a little on the slow side?

Supposed 2800 stall that only stalls at 2000

Pull that stall back out and make the shop reset it to at least 2800.
The near stock stall coupled with your taller tire is probably whats hurting your times.
