85 k-20 Drivetrain

[67TexasC-10]

I have a 1985 K-20 that is lifted 6 inches with 4.10 gears and 33 inch tires...(35s in near future)
It currently has no motor trans or tcase...
Before it had a pretty stock 350 with an sm465 and an np205 i believe...
I know have a 350 out of a nova than ran 11s to put in it... it is backed by a 2wd turbo 350.... minus the fact of no 4wd what would it be like to have that setup in this truck....? It is going to be a daily driver that will tow the occasional trailer of up to 5000 lbs? And do some moderate mudding and trail ride as well as pullin people out... Shuld i switch back to an sm465... an nv4500? what transfercase should i use? np205? Has anyone ever used a gearvendors unit on either transmission? I would like to get it goin as fast and cheap as possible! Also oklahoma to Texas drives will be made often!

Thanks-Blake
