Is this an IHRA class car or a NHRA SS/CS car and what is the low gear ratio? If it is a NHRA class car and your engine is built for high RPMs I believe your problem or at least part of it is your rear gear ratio. My NHRA SS/CS car uses a 6:20 rear gear and a 2:08 1st gear and uses a 7" converter that flashes to around 7600 with the 60's in the low 1.30's.
