thanks for all that.
car is on ladder bars, 275 Hoosier radial( 28 by 10) 4.30 gear.
It is a PTC 8 inch. I had it adjusted once already to the 360 I had in the car previously by Jason at Quick Draw Convertors in Ohio.
He comes highly recommended by guys I know who are veteran racers.
I definitely want to adjust the vert, if I do the low gear set, it would need to be at the same time I send the vert out.
Decisions, decisions .
what I really wish is I had a spare good footbrake transmission to swap in, and shelve my brake tranny after freshening it( don’t use the brake in it currently)
