    I'd say 5.13's would be better. With 4.56's you'd be turning a little over 2200 RPM at 65 MPH on 44's. Thats kinda low and those 44's would be heavy! Having a small block sure doesn't help...

    I'm running 410's with 44"s , sm465/205., big block

    I get away with it cause of the sm465 and big block

    I would definately recommend 5.13's or lower

    Lower would be cool, but 5.13 is as low as you can go with the 14 bolt FF.

    4.56's won't be a problem with the 44's, Paul Cooper out here runs that in his big Ford without any troubles. He's got a 460, and the truck doesn't see pavement any more. If you're worried, go dual T-case, it'll likely be cheaper than regearing both diff's.

    that is the best advice i have seen.
    no way would i run less then 4.88-5.13 on 44s
    i run 4.88 with my 39s as it was a dog with 4.10 pulling away from uphill stoplights

    My dad use to have an old 75 Dodge 1/2 ton truck with 2.73s and 44s. It was slow but the tranny never went out. The top speed with you foot to the floor was 65mph. It had 1/2 ton axles, automatic transmision, and a stock 318. Never had any problems with it, but mostly did mud bogging.

    I ran 4:56's with my 44's for 2 years and had no problems with my stock 350, and then I went down to 38's and later changed to 4:88's which I love !!

    My friend has an '80 K20 Sub with a 350/SM 465, 4.56s, and 44s. It goes along just nicely.

    This was in another post by Tim...

    <blockquote><font class="small">In reply to:</font><hr>

    Since I'm planning on 37s, I was planning on 4.88 gears. Maybe that wouldn't even be enough.

    This was in this post...

    Different tranny rusty--I've got a 700R4, he has an SM 465.

    Like I've said at least a half a dozen times to you--I am not the moron you think I am.

    I am now planning an SM 465 swap (tranny's in the garage) so I'm keeping my 4.10 gears and going with bigger tires because of the lack of overdrive.
