56 3600 SBC/4WD Trans Question
Hey guys,
I have a 383 stroker I built from a 73 vette's 350. I am going to do a 4WD conversion on my truck and I already have an np205 transfer case. I will most likely be running Dana 44 in the front and corporate 12 in the rear. 383 will be putting out about 400 hp and 450 ft lbs of torque. I am looking for a 5-speed manual w/ overdrive. I heard good things about the NV4500 and I know it hooks up with the SBC and np205, but I also believe it is a low-geared slow-shifting truck tranny? Mainly this truck is going to be powerful, the 4WD conversion is only for snowy winters. I need the overdrive for 3 hours of daily highway/country road commuting and I would like a sportier transmission. I was looking for more of something like the Tremec TKO, but I don't believe it will work with the np205. Any ideas? |

I would go with a divorced NP205 from an early to mid 70s Dodge, that way you can run any Trans you can come up with and not have to worry about adapting a Trans to work.

I would do the nv4500 with the adapter kit to use the np205 on it.But what size tires are you going to run on it?

If you decide on an nv4500 use a 95+ version. 1st gear isn't as low and the gears are spaced more closely together.

Re: 56 3600 SBC/4WD Trans Question
I am pretty sure I will be going with 3.73 gears and about 29" tires. After doing some more research, I am leaning back towards the nv4500/np205 again. This thing is going to be heavy and possible tow the snowmobiles back and forth from Rhode Island to Maine.
