I am going from a 2.8 5-speed to a 350/350 automatic. what kind of crossmember do I need, or can i use the one that I have with some modifications?

'82-'83 4-speed manual or 3-speed auto will work.

Or get one from Spohn that'll mount the torque arm as well.

My 84 was originally a 2.8 5 speed. The stock crossmember worked without any modifications when switching to a v8. I did buy the B&M tranny torque arm mount to hook up the torque arm.

A stock crossmember is about $10 at your local Chevy dealer.

Which TH350 did you use?

Guess it wouldn't matter. The bellhousing to crossmember mount distance would be the same regardless of tailshaft length.

The kit is for the 9" tail shaft , but i modified it to work with my 6".

crossmembers the same

have to get B&M or similar torque arm mounting kit if the tranny you are putting in does not have the holes through the tailshaft housing for the bolts- Ie a tranny not stock factory for an 82-up F body

ive been through all this with the th350 swap in my 82 t/a


good luck

Just something to consider.

It worked that way for you because you started out with an '82 chassis. A TH350 works fine in '82/'83 models with with the only thing needing to change being the torque arm mount.

Later chassis used a longer transmission - the mount was farther back in the chassis than it was in '82/'83 with 3-speed automatic or 4-speed manual.

When you go to a TH350 in a car that came with a 5-speed manual or TH700, you need to move the mount location forward a couple of inches. The bellhousing to mount distance on a TH700 (or 5-speed) is 22-1/2", same dimension for a TH350 is 20-3/8".
