I have all the numbers for a stick car which is my intent BUT if I have to go automatic weapon 3 speed-----anyone care to suggest a gear ratio for a 327/274 Chevy ll stocker---3005 lbs---30" tire----three speed metric auto ???? I would love to get it right the first time. THANKS for any intelligent replys.

Re: Rear gear selection for Chevy ll 327 stocker build......
MPH X Gear ratio X 336 divided by tire height = RPM.
You'll have to allow for converter slippage someone else could tell you more on that # but probaly 5-8% would be good guess as example figures crossing @ 7100 add 8% would be 7668 Stick car will match formula almost exactly. Can also figure converter % slippage@ top end w/this formula as close as can for guys without data recorder Mike Taylor 3601 |

Re: Rear gear selection for Chevy ll 327 stocker build......
I run 5:13 in my wagon (350/2bbl/Glide) in P/SA @ 3850 lbs or so
Its got a 28.5 Goodyear ( I forget the roll out) One friend runs (350/4bbl/Metric200) 69 Camaro in G/SA uses 5:13 with 30.0 ( Hoosier, I think) Another friend 350/2bbl 69 Camaro M/Stick uses 5:13 with 30.0 M/T Don`t have roll out #`s for those Most people I talk to that run SBC Stockers run 5:13`s Just my two cents Good luck Last edited by Mike Jones; 03-06-2014 at 09:40 AM.

I am inclined to agree with Mr. Lewis. Car is really light and in testing not much difference but consistency.
