    I read Zakk's post about 5.13's but still not sure. I run about 2500 RPMs going down the highway right now, with Blazer in my sig. The tires are really 41" tall. I have a TH350/NP205. So I am turning to everyone here for their options. Thanks for your time.

    P.S. I do drive this daily and I make 200 miles round trips on the weekends.

    you know what I voted for! /forums/images/graemlins/thumb.gif

    I turn about 3200 RPM's at 65 MPH. I'm running tiny, little 40's so your 44's will do much better Plus, with the added weight of your rolling assembly (IIRC, 44" TSL's weight ~115# each...without a rim!) the 5.13s will give you more mechanical advantage to get them moving. and a BBC won't hurt either!

    I've only got a little SBC 350 that pumps out maaaaaaaaaaaybe 250 HP and the 5.13's are still good. I just need to get my overheating problems in line /forums/images/graemlins/crazy.gif

    not to be rude, but your running 44's. 5.13's are about your only choice, unless you want to swap to a D70 rear and run 5.86's.

    my post about 5.13 were directed to the 700R crowd with 35-37" tires. with a TH350 and 44's, you need all the help you can get to move those tires and not burn up your tranny.

    So the gear change should not make my big block turn to many RPM's.

    randy's gear calculator says you'll be at 2700 RPM's at 65 MPH

    but you didn't drop in a big block and add 44" tires for their gas savings!
