Here's an odd one (maybe). As I was pulling the 350 out of my '68 I noticed that the engine was tilted down at the front. In fact, the plastic timing gauge had a 3/8" groove in it from rubbing on the pulley below (maybe wrong gauge). I couldn't even remove the belt as that pulley had dropped down into the grooves on the crossmember.

Motor mounts are correct and the height of them looks perfect. No squish there. The previous owner, however, had replaced the Power Glide with a Turbo 400 tranny. The tranny crossmember came from a '67 Camaro according to the paint crayon markings.

The tranny crossmembers are interchangeable between Firebirds and Kamaros right?

the crossmembers should be the same. the only camaros which had th400's also had big blocks i think.

there are two heights of transmission mount for the th400. one is about an inch taller than the other. seems like you have something else going on tho' i cant for sure think of what.

Wow? That seems like quite a bit of tilt? It sounds like that is the problem?

I would take your current crossmember, and see if you can compare it to another one at say a junk yard... or some place local that may have a few?

Maybe, some how the previous owner installed it upside down? Or something really strange like that? But it wouldn't take much height change at the tail shaft to make a large change at the front of the engine...

Hope you get it figured out! Let us know what you find!

Brett - The crossmember was definitely in the correct position. Scott - An extra inch on the tranny mount could definitely be the culprit. Thanks!

Anyone know how to determine which tranny mount should be used with my TH400?

- Jake

i would say for sure you should have the short one.
when i went to NAPA they listed both for a '68 bird, and did not say why. they had both in stock, and there is a big difference.
perhaps the tall one is actually for the st300? i said specifically th400, but maybe their book knows no better.
how tall is your current mount?

OK ... this may be way off base ... but was the cross-member installed up-side-down?

Q

Q,

No, the crossmember wasn't installed upside down. In fact, that was my first thought too. I even had to double-check just to be sure.

Just thought I'd check. There's no end to the funky stuff I've seen done on cars. Sounds like the trans mount might be the ticket.

Q

is the cross member tubeular or channel firebirds are tubeular some camaros are channel my 67 has your basic rear mount i could send you a pic of this

Rick,

The crossmember is tubular. The rubber on the tranny mount is exactly 1.25" thick. I'd love a picture - thanks. E-mail or snail-mail? My e-mail address is: www.jacobson2000@comcast.net

Thanks!

i think you already have the short mount. 1.25" is pretty short.
maybe the crossmember got bent somehow?
maybe there really is a difference in the camaro part?
or maybe it's something else altogether.
