9'' non race ring and pinnion ?
Hey guys, I bought a 9'' 3rd member with a 5.67 gear set off RJ just to test the et and rpm difference in the 1/8 mile from my 5.14. and if it works out I'm gonna change my gear set in the one that's in the car now because it looks twice as strong as the one I bought . The 5.67 I bought to test has a spool and a Motive gear in it and it's not stamped 9310 or 8620 but I think it is the 8620 by the #'s I pulled up and it does NOT have a after market large pinnion suport. it looks stock . question is will it hold up if I don't use my trans brake and just foot brake with a 670 H/P 2675 # car with a glide long enough to see if the gear ratio is going to work for me or not I only need a couple passes, { this one came out of a circle track car}
Thanks Andy
