Rusty Jeep Posted February 3, 2021 Author Share Posted February 3, 2021 I've got a 350 that makes around 300hp. so i'm thinking nv4500 will be the best rout to take. Link to comment Share on other sites More sharing options...
89 MJ Posted February 3, 2021 Share Posted February 3, 2021 My dad has an NV3550 (maybe 3500) in his 5.3 YJ on 35s. Its beat on and has held up. Link to comment Share on other sites More sharing options...
Rusty Jeep Posted February 3, 2021 Author Share Posted February 3, 2021 I don't think the nv3500 will work with a 350 from 1974 unless i'm wrong. Link to comment Share on other sites More sharing options...

You can find factory parts to bolt them up easily. The 4.3 V6 came with a 3500 and uses the same bellhousing. Get a standard flywheel for the 350 (may be the same as the 4.3) and the right clutch parts and it all goes together easily. Link to comment Share on other sites More sharing options...
Rusty Jeep Posted February 3, 2021 Author Share Posted February 3, 2021 I'm still a little hesitant that the 3500 will be strong enough. Link to comment Share on other sites More sharing options...
derf Posted February 3, 2021 Share Posted February 3, 2021 Then run a 4500. Plenty of them in full size Chevy pickups starting in around 1993 or so. Link to comment Share on other sites More sharing options...
89 MJ Posted February 3, 2021 Share Posted February 3, 2021 Are you going to beat on your truck? My dads YJ with 35s, a 340 hp 5.3, and an NV3500 has done several burnouts and donuts on the pavement with no breakage. I think you’ll be fine. The 3500 came in half ton trucks too.

Rusty Jeep Posted February 4, 2021 Author Share Posted February 4, 2021 I want to be able stick the pedal to the floor with blowing the transmission. Is that transmission in your dads YJ stock internals or is it built. Link to comment Share on other sites More sharing options...

And my second question is will the nv4500 fit in a comanche? I would think you would have to do some tunnel bodywork to get a NV4500 to fit.

Pete M Posted February 4, 2021 Share Posted February 4, 2021 the 4500 is a giant heavy beast that has a granny first and is not much fun to shift. Link to comment Share on other sites More sharing options...
Rusty Jeep Posted February 11, 2021 Author Share Posted February 11, 2021 Does anyone know if the gm power steering lines will screw right into the factory steering box? Link to comment Share on other sites More sharing options...
derf Posted February 11, 2021 Share Posted February 11, 2021 Unlikely. You'll probably need custom lines. Link to comment Share on other sites More sharing options...

MiNi Beast Posted February 25, 2021 Share Posted February 25, 2021 saginaw boxes should be same, and 8.8 with 4.56s. Link to comment Share on other sites More sharing options...

I would choose 3.73, but 4.10 wouldn't over rev it with an overdrive. Really depends on tire size, and I don't think I saw that anywhere. Link to comment Share on other sites More sharing options...
Rusty Jeep Posted March 10, 2021 Author Share Posted March 10, 2021 Does anyone make the sbc motor mounts for the comanche other than novak. Having a pretty tight budget I'm wondering if there is any cheaper options. Link to comment Share on other sites More sharing options...

Rusty Jeep Posted May 6, 2021 Author Share Posted May 6, 2021 I have a 350 in front of an nv3500. I know there is two different size flywheels. I don't know what will work best. Link to comment Share on other sites More sharing options...
