that'll be a little hard to do if you plan on running the car in 2017 if you are using that look under to determine what rear axle you'll use.

I'll save you some time, almost all will be the type O (and some will have some steep gears like mine - hint hint). I know Dave H had a C 12 bolt at one point under the Ram Rod. I also know he swapped it back to a type O. He may have C 12 under the 66 now, I'm not sure.

and to make you feel part of the PSMCDR participant family, I'll break you in now. So get used to this banter - cheater [img]<<GRAEMLIN_URL>>/laugh.gif[/img] [img]<<GRAEMLIN_URL>>/laugh.gif[/img]

Seriously though, I do understand the C 12 bolt usage. But if you are getting the max'd out MASCAR motor, I HIGHLY recommend some steep gears. 3.23s and 3.42s won't cut it. Don't be afraid of the 4.33s. 3.91s would be the bare min I would consider for a high winding small block. In C 12 bolt speak, I believe 3.90, 4.33 and 4.56 are your options.

FWIW, the racin cajun ripped the pinon out of the 9&quot; Ford of his BOSS 351 at Stanton, so anything is possible
