Got first runs on my truck this weekend at PAO in Joliet and need some work but I am happy for the first passes it didn't do anything stupid. My combo 2000 Ford Ranger with 523 TFS Street headed motor at 10.87:1 C-6 with 4000 stall and 4.11 gears. Cam is Howards solid roller 258/[email protected]" with .692/.692" lift. Timing is 14 initial and 32 total. First run was [email protected] with shift at 5000 and a 6000 chip in the box. Second pass was [email protected] with shift at 6000 rpms and 7000 rpm chip in the box. I have 28 inch tall m/t et's. On first pass I hit the chip over a hundred feet before the 1000' mark and second pass hit the chip about 100" before the strip. I realize I need a lower numerically gear but is there something else that I should do to improve my times or just wait til I get the right gears? Thanks in advance. I am happy though as these were my 2 quickest passes ever.
