I am going to try to dyno it at the place that Andy F does his dynoing. They are good guys there and real smart with alky injected stuff. This way it will be close at least when I get it to the track. I turned my old w2 stuff to 7500 every pass. I want to keep the revs down if I can. Stock block. I crossed at 7450 with old combo at 134.80 with 29.5 tire. What gear do you guys think with the new combo?? 4.30s or 4.10s??
