i have a buddy who is  rebuilding his whole truck, and considering these 3 engines, i want the pros and cons and what trannys he can use, he really wants to use a Chevy nv4500 and don't want a auto, and plans on using a atlas 4 speed. any feed back would be sweet! thanks

Unless he wants adapters, a 4.3 is the way to go.  I woulds go with an SM465 tranny and get that granny low,  he'll be crawling lower than most with the atlas in High.

1uzfe would be sweet tho

ya he really want to run a nv4500, maybe thinkin about Buick v6 turbo supercharged or na

Since the 1uz weighs the same as a 3rz. And its still all toyota, which I happen to still like. I vote 1uz.

Unless you have deep pockets it's all about what's available.
Thats how I decided what motor to swap in. A 4.3 opportunity presented it's self and I took it.

[83 Crawler [OP]]

I think he's going 4.3 so he can run a nv4500 tranny I don't think he can run that if he gets a 1uz

[yotaneck13]

you can run any tranny you want behind any motor with adapters

[83 Crawler [OP]]

No buddy makes that adapter iv looked around

Just put in the R tranny, it will handle the power with room to spare.

yup thats why he wants that tranny for the compond low

[4RunnerChevy]

4.3 it is then   

[83 Crawler [OP]]

yup im thinkin so or a 5.3

[TacoRunner]

Interesting, I have the 4.31 1st in my R, and I dont like it for the street at all. Its way to low.

[83 Crawler [OP]]

his is going to be only trailer truck no road. thats why he wants the super low first gear

4.3 you dont need the V-8. The weight over power gain in a Toyota is not enough to make it worth it.

[83 Crawler [OP]]

ya 4.3 is probley
