Whats up?
I had performed this swap on my Iroc a couple of years ago. The main things you're going to need is:
1. The B&M adapter that secures the torque arm on the side of the 350 tranny.
2. Cross member from the older 82-84 model camaro/firebirds that came with the 200turbo metric 3 speed trans. ( under your car there are 3 bolt holes per side that the cross member can bolts to. Of the 3 holes only 2 are used per side to support the crossmember/tranny assembly.
3. Tranny choices are the long tail 350 or the short tail 350 trans. The easiest would be the long tail because you get to use your stock 700r4 drive shaft! If you go the short tail route. You will have to buy the drive shaft that came out of the car that had the 200 metric 3 speed trans in it.
4. Last but not least your going to need a 3speed shifter. You could also use the same one that came out of the donor 3 speed car. |
