    I may have a lead to some 1/2 ton diffs w/ 4.56s. (12 bolt/ Dana 44.) If I do lift my 84, it's gonna get some 33s. Went to 4lo.com to screw with the gear figure thingamerbobber, and I found out that O/D w/ 33s an 4.56s at 65MPH has an RPM of around 2292.. Not sure what that signifies, but I was just wondering if this is a good idea. I thought that 4.56s may be a bit too low for city driving.. but I dunno. I want some input before I decide on anything

    I know a few guys that run 4.56 with 33's and 700R4's - they swear it's the best combo out there - about like running 4.10's with a SM465.

    Clean up on aisle 3!!

    I have that set up. I turn about 2600 rpm at 70-75 mph. If you have OD, you will like it. It also leaves room to go to a bigger tire later on.

    That is exactly what I have. I love it. 2200 rpms is right in the power band for the 350. You won't regret it...Dan

    If it ain't broke.......Don't fix it....
