If you drive like me, a wuss, you'll see an improvement in fuel economy.

You'll miss granny though.

Re: 292 with 700R

Looking at doing this with my 250 now. Got a rebuilt 2004r going in. Has a a higher 1st gear (Better for 3.73 rear) and a slightly lower OD. Should get my RPMs down to 1900-2000 on the Highway. Plus it is the same length as a TH350 so I shouldnt have to shorten the driveshaft.
