With the bigger heads and 112lsa cam I can easily imagine where it would want to be shifted at 6000-ish for the best ET.


Ok, gotcha... yeah on that 12.55 pass I was thru the traps around 5k.. and just left the trans in Drive. It was probably shifting around 4,200. I plan on upgrading to full manual valve body down the road to better control my shift points. I know I'm leaving a lot on the table just making passes in drive, but I'm not a very experienced track guy. I still need a LOT of practice... lol.
