Theres three T56 box ratios, inc one with a mega long 0.5 6th gear (the other 2 have .62 ratio 6ths).

What car is that super long one off?

Anyone know? Marco? Sheady? Bernie?

Dunno. But i'm pretty sure I can get the one marco has in his car if you want one. Think it's out of a Camaro?

The Corvette T56 had the tall top as a option plus has the best [triple cone] syncromesh
