Question !!! I just bought an IHRA crate 85 z28 and i cannot get it to 60 ft the same as the last owner.The only change is the trans,same convertor i suspect the prob is i am running a 1.96 gear set and i am thinking previous trans might of had a different gear.Its a glide with a brake and 4.88 gears 60 ft is 1.48 and some old slips with car show 1.40 so just wondering what first gear ratio i should be running 2.08 or higher ? It is 350 330 hp car Thanks
