VCCA Home Forums TECHNICAL - 1945 AND NEWER 1965-1970 1967 Camaro 327 & 4-Speed Manual Transmission Install Problem

Yesterday, Cousin Dave & I were finally (!) installing the 327 and 4-Speed Manual Transmission into my 1967 Camaro Coupe. It was going fairly well - we didn't run into the firewall or anything else while dropping the combination in. Engine mounts lined up perfectly, but when I went to mount the transmission to the crossmember, I'm about 2 inches short of the transmission mount! See photo. From everything I've seen, there is only one crossmember for a small block installation, no matter if it's a manual or automatic transmission. While this car started life as a 6 cylinder with a Powerglide, it looks like the crossmember was still the same. What am I missing? Why doesn't my transmission line up with the crossmember transmission mount? The Muncie 4-Speed transmission has the 3885010 case with a 3846429 tail shaft. I've also compared the 429 tail shaft to a 3857584 tail shaft (difference as to where the speedometer cable is attached), but they seem to measure exactly the same in terms of length and position of transmission mounting. Is this potentially a Muncie vs Saginaw 4-Speed transmission issue?? Any thoughts appreciated!!

There is another rear crossmember mount available, that I believe will solve your issue. Here is a link, look at the first and last one listed. Bob

Thx. Yes, I've looked at those - I've bought a lot of my parts from Heartbeatcity. They specifically say those crossmembers are for TH-400 automatic transmission installs. There's no way to tell what that offset is from the pictures. I just called them and sent them the photo. At first glance, they don't think the automatic crossmember has any application for a manual install, but they're going to show it around.

Just in case anyone wants to know, the problem is solved. Turns out that if the car was originally a six cylinder you basically have to swap the motor mounts from one side to the other. The engine mounting portion of the mount is offset, so with the swap it moved the assembly back 2 inches. The transmission is now bolted in and the restoration can continue!

I look forward to seeing the Camaro on the road.

Great to hear that you solved that dilemma. That looks like a very clean car and drivetrain. Should be a great car to drive.

Will you need to add a fan shroud due to the shorter engine and the fact that the reversed mounts moved everything 2” to the rear?

Rusty -

Yes, the V-8 install definitely requires a fan shroud. One of the many things on my list to buy... :-)
