Ok so here is a little history

82 short box
68 3oo hrs vette 350 ( demon 650, fuile big valve heads)
ford posi 9 in rear 3:92/2:02 cruising open chunk

Currently I have a dieing 350TH Tranny

This truck is strictley a hobbie truck it gets driven rarely for some crusing and roding but when I do drive it I DRIVE it
So here is my question,

I have heard from a few Local hot rod guys That I can use a five speed from a 4.3 litre v6
I have also heard that this tranny will not hold up.


I also have a sag 4 speed that has been gone thru and is fresh
I know that the sag will work for a while but again depending on who I talk to
its good and bad.

I want the overdrive option so that I dont have to change my rear chunk so much when I take it on distance cruise
I also would rather have a manual than an auto

So I know about the after market world but its a little too spendy for me

Please let me know what your opinion is on the two trannys I have and maybee another option that you know of

PLease keep in mind its on a strict budget

Thanks to all
