Finally hit the 12.52 last week with my 98 transam. 1.66 60 foot .0047 react time....107 MPH
Putting in a yank SS4000 with a 3.90 and a stage 4 Transmission. Got me there, engine is pretty much stock. Just picked up some 243 heads that will get CNC'd and a nice 224/228 cam. hopefully then next post will be in the 11's
