Doug Nash 4+1 Crash Box Pro-Shift Drag Race Transmission
 

For GM applications - Pontiac, SBC, BBC, Buick, Olds. Set up for "Hemi" clutch disc and slip yoke for maximum strength (not included). I bought this for a project and ended up not using it. According to the the guy I got it from, it was just freshened up, and it does look like it's in excellent shape. This is about the strongest race transmission setup you can get without going to a high-dollar Lenco, Liberty, Jericho, etc. $1500.

what are the gear ratios?

Not exactly sure. First gear is around 3.0-3.1 to 1, which I determined by counting turns. Tooth counts for the five mainshaft gears are 39-33-28-24-24.

hmm, is there a shfter and likage included? Let me do some more thinking.

Richmond used to could use the serial # and look up the ratios it was shipped with. I've got some catalogs that have what ratio they are also from tooth counts.

it's now up on ebay, ends tonite
