high speed rear end question

I have a 1930 TS and several years ago decided to set it up for touring and also just regular fast cruising here in S. Calif. So I had the Snyder 5.5 head installed, along with the Mitchell OD....it is a great combination, even if you don't tour. I like to drive 55 or so, and it is amazing how quiet a nice running A is with the OD, and with the HC head it pulls it very nice, even up gently grades. The Mitchell is expensive, but one ride in a car with it is an eye opener!

Not horsepower but here are some numbers for you,
2000x14.75 (1/2 tire dia)=29500
3.54x.72% overdrive=2.35x168=395 (rounded off)
29500 divided by 395= 74.68 MPH @ 2000 RPM's

Take a few horse's for that
 
I have had a 3.54 rear end on backorder for the last two weeks. I don't have a high compression head but plan on one at some point in the future - probably along with a new head gasket if and when needed. Hopefully my coupe will pull fine with it since its lighter than other models. In an ideal world I'd go standard and get a michell OD but there are many other things I'd want to spend that kind of money on first like tires and shocks. I'm anxious to see how it drives when I get it back together! Hopefully soon! In the meantime I'll keep incessantly checking my email and doorstep waiting for that darn gear to ship/arrive! :rolleyes:

I don't know what your ratio is right now, but I'd think the S-10 5 speed and stock 3.78 would be about the best ratio. Adding a 3.27 to a S10 5 speed would be pushing it over the limit.
 
brent / tom , i have 3.78 now , but cant quit get where i want to be on high way rpm . the low gear in the s-10 is plenty low for a higher rear , but as you said the 3.27 maybe to high . i also have 31" rear tires . brent ... what is your set-up ? tom that is what im afraid of , over the top . thanks guys !
