is it worth to replace my TH350/NP203 with a 700R4/NP208 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

been thinking about finding a 700R4/NP208 or NP241 pullout from a newer truck and swaping it for my TH350/NP203. my TH350 is only 1 year old and the transfer case works fine, i want overdrive and cant stand how the NP203 is full time 4wheel drive. ive heard the NP208 and NP241 are kinda sissy cases and cant take much abuse even tho they are chain driven just like the NP203. i would LOVE an NP205 but i think the cheapest way to do this swap is to find a 700R4 with NP208 and the driveshafts from a newer truck. is this swap worth it or is this newer combo not as strong as my current setup? thanks

what are your plans for the truck? mild off road the 208 will be fine and you will love having overdrive, plus the 208 has a lower gear.

I just put the 700r4 and np 208 in my 61. I love the overdrive, but its not a hardcore wheeler either. I think its good for general use, and playing around with. It just depends on what your going to do with the truck.

I had a np208 in a street stock pulling truck for four years and never had a problem.I went threw 3 clutches, 1 front axle,1 rear yoke,2 engines.Unless you plan on rock crawling you'll be fine.
