The cost is tough but I'll give it a shot, been about 6yrs!
motor: 1967 283ci block was given to me, put about $b00 into heads, machine work, rebuild kit, and intake/carb
Tranny: got th350 for $125 from a yard, put $250 into a warrantied rebuilt kit.
np231 to th350 adapter: about $450
Motor mounts: $75
ratchet shifter: $160
misc sh!t: $200 (you'll be surprised how just bolts and stuff add up)
But I would say if I bought a stock YJ today and somebody gave me the 350 and TH350, It would probably cost an additional $800 to get it in???
Go with the TH350, I would't take chances with the stock one.
The only thing I wish I would have done is just stay chevy all the way though (i.e. a chevy 205 or 205 tans. case) and put a different front axle with a passenger drop pumpkin. That is coming up within the next year or two hpefully
I still need to get my ford 8.8"
