Hey im switching transmissions in my 86 k35 and need to know if a sm465 transmission (out of a k20) will fit on a 6.2? Also i need to know if a np208 (4wd transfercase out of a k35) will go on the 4 speed transmission?

 

i dont know and if no one answers you here i would join a offroad truck forum and ask them. the type of people that are into swapping t-cases and trannys all the time. there the people to ask

 

i am not very furmiliar with the 6.2s but i was told that they were made with the chevy 350 block if that is the case then the sm465 will bolt up to it. i think the only difference might be the flywheel and clutch size if anything and mabye the pilot bearing hole might be different in the crankshaft. as far as the t case goes i would say that you will probably have to get another transmission to t case adapter and it should work. those are just a few things i would check before spending too much time and money on it.

 

I'll ask on an offroad site but i think your right cfarley, i have the two trucks so i mind as well try couldnt hurt. Thanks

 

The 6.2 comes over to about a 373 ci. So it'll be a big block like the 454. On the transmission, if it came out of a 4x4, it'll work. If not, your going to need a longer output shaft.

 

well the transmission is out of a 2wd truck, the engine and the transfer case is out of a 4wd truck. So will the engine a transmission fit and will the transfer case fit on the transmission, or just one or the other? I'd rather have the adapters i need (if I need any) before i start tearing into this project and get stuck waitingfor a hard to find adapter to come.

 

the tranny output shaft most likely wont work for a 4x4. depending on what the t case is out of you might need a different adapter to the tranny. if it is a chevy bb it will mount up. i am just not sure about the clutch and pilot bearing but most likely it should work. it sounds like your getting into a big head ache of a project. im not trying to discourage you but i have had projects like that and it seems like everything goes wrong and they are just a pain.

 

ya, been there done that also but i really want to put the 4 speed in the truck, and get ride of the th400 b/c it slips terrible.

 

call advance adapter for the parts needed to mate what u want they have everthing, did my truck with their adapters.Swap experts

also if money is not to tight you can order an atlas transfer case to fit your application and dump that chain drive case.

 

sm 465 to a np205 are not hard to find i even have one for sale but i do know for a gasser that a small block bell housing and a big block bell housing are the same i have heard that the bell housings are the same on a 6.2 to a gasser but i have never done the swap my self but if i were u i would just go with the 4x4 trans mission and not deal with the the sm465 are not really fun to take apart
