Need th400 crossmember!!

Does anyone have a th400 crossmember that will fit my 1972 chevy nova? If so, please include shipping to South Gate, California 90280. It could be used as long as it is still in good condition. My e-mail is novamuscle@sbcglobal.net

I am planning on replacing my shot th350 with a th400.

thanks....

Why don't you just use your current one?

Looking at my current set up with the th350, I noticed that my crossmember looks nothing like the ones that are used for the th400. The one I have is kind of straight were the other kind that I see on ebay have a "U" on it that helps with the clearance of the trans oil pan.

You think that I can still use the crossmember that I have without modifing it?

Have you looked at jegs or JC whitney? Look at some of the big catalog places like them or year one or paddock.

Your Nova uses the same crossmember as a '67-69 Camaro w/T400. They are available at Camaro restoration parts dealers. They were only used with big-block cars, which had the motors offset to the right a little bit, so you may have to enlarge the holes on the trans mounting tab.

Not sure about the Nova, but that year in pickup trucks had the frame drilled for different trannys and you just slide the crossmember to match the holes in the frame when going from say a Turbo 350 to a Turbo 400.

The crooked, oval cross member was used on big block with 400.
Every thing else used the flat cross member.

If yours is a SB, then your old member will move back to another set of holes and work.

On a '72 Nova, there is only one set of holes in the subframe for crossmember mounting. The T400 crossmember just has the center trans mount holes farther to the rear, & is shaped different due to the size & shape of the T400 trans.


The '68-'72 Nova uses the same subframe as a '67-'69 Camaro, & the crossmembers work on either car. I got one for my '69 Nova from Rick's (also stole the pic from them) about 3 years ago for ~$50.

It won't fit. The crossmember barely clears the oilpan from the th350. Besides I'm planning on a big block in the near future to be added.
