NV3500 in my 74 Duster?

Interesting trans mount.

Looks like no floor cutting. That's cool.
Was there banging of the tunnel?

Our P/T "likes" to be shifted between 3K and 3500.
I'll have to check the speed at that RPM.

Seems like a trans with a low first would like a higher rear.
Might try 2.94...

When i was test fitting the trany there was a lip that was sticking out where the firewall and floor was welded together in the tunnel so i bent that to clear the bellhousing, that was the only banging i did and the shifter is located close to the tailshaft housing.
Ive had 2.79s in the rear before and 1st gear was alot beter but the change from 1st to second kinda sucked. Also stepd up to 3.00 gears and it was about right, but i finally installed 3.25s and i think is ok, can even start it from the get go in second with alittle ease, but i think max is 3.40s anything more it would be low as hell which you might as well launch off in second, lol
Also The torsion bar crossmember where the center is, i only cut it half off to clear the tail housing and i moved the engine foward 1 inch by modifying the motor mounts to clear that area, I was really skeptical about removing that whole center section because ive seen other members do it so i did it this way to keep some structural integrity. Its a tighter fit close to the shifter mounting area and alittle more work but another forum member which i cant remember who it was that i got info on this trany swap did it another way which i think was alot easier. I just went this route which was kinda retarted but it worked out for me and i was able to use the stock driveshaft.:D
