LSx to sm465

[mikevogt]

Hey guys so I picked up a 69 c10 a few weekends ago. Has a 6cylinder in it but it is not hooked up or anything due to the old motor throwing a rod. My plans were to do a 4bt cummins but for the price/work to do it not really wanting to go that route. I already have a newer diesel truck anyways. So the question here is keeping the stock 4 speed to the LS. I know I need the newer truck flywheel, 11/12in pressureplate, ls7 pilot bearing/bushing. The real question is from what Ive seen I wont need a different bell housing? I am aware not all the bolts line up which isnt a big deal. Before anyone says anything I do not want a auto or a t56, I already have a race car so all I want this truck for is to blast around town in. Thanks for any info I appreciate it.

Here is a picture of the truck.

How would a t56 prevent you from "blasting around town", any differently from the 4speed?

The most recent hot rod magazine had an article exactly about this.

Looks like a '67 to me.

This is a 4x4 but should have some info

Nothing wrong with your setup man I am keeping my TH350 cause I dont need an overdrive and it is a brand new trans

Probably just replacement fenders as I see 6 lugs but 20 badges

I noticed that truck when I picked up my FRS wheels a couple months ago

Go for it! The only thing I remember possibly being an issue is the mechanical clutch linkage...

^Correct just has 20 badges on it not really sure why.

I despise t56's, they cost way to much money and break constantly. Plus they feel terrible also. So yeah I rather spend 4-500 bucks to make the 4 speed work vs 2 grand on a t56. If I was spending that much money to make it a 6 speed id put a nissan 350z trans behind it most likely.

You won't find the z's tranny for less than a t56, and the Mazworks adapter plates run around $450 last time I checked. We have a Z kicking around here waiting to kill the VQ (it'll be a while), so we can make use of this ls2.

Im not saying it would cost less. I had a z trans on a 1uz lexus v8 and only spent 300 bucks on the trans but all said and done probably cost 1500-2grand to adapt it.

The nv4500 weighs a little less, you get the extra gear as well....tho sometimes getting one for 2wd behind an LS motor isnt the most plentiful option.

What did the nv4500 come in? I remember my old cummins dually had that trans in it.

Starting in late 93 you could get them in Dodge and GM trucks. The actual Dodge vs GM nv4500's are a bit different in terms of speedo output etc. First place I saw them was medium duty GM stuff like UPS trucks. The designation is MT8 or gm #12346190

Bottom line, on the cheap, use your existing bellhousing, you will be shy 1 bolt, won't hurt a thing,

Then all your clutch linkage, etc. will still be there.

You do have to use the LS flywheel, clutch and I believe a LS2 Pilot adapter?

You also need to get a pulse generator for the vehicle speed sensor.
I think Dakota Digital has something for this, though I eventually just went 4L60E.
I think an SBC bell housing will work but I don't know about the I6 pattern. If it's the same as the 90 degree 8 cylinder block pattern, and the starter hump is in the right place, it should work fine.
