Thought so

The rear corner of the driver side looks to not be a 90° angle at the corner. I said passenger side in my first post, when I actually meant drivers side. I'm still thinking 350.

It's a 400. Mine has the same dish in the pan on the passenger side rear. Also from this photo you can see the cases look totally different. The TH-350 is not showing the vacuum modulator near the "0" in 350.

Since you dont have the ecm and complete harness your options are try to find another harness and ecm to install or an intake manifold with the correct bolt holes and pattern to match your carb.

What is the difference between that and the 350C. I have one and it has a odd modulator/pan/torque converter setup. Had hell when my modulator went out to find the correct one..

Okay I finally did it, removed the front clip Monday after cutting 3 acres of grass and cutting down a pin oak tree in the front yard.

Just to clarify I was able to get the engine setting in the truck, then move the trailer and engine hoist and set it ( the hoist) up on the ground and get the motor on the mounts, all done without a scratch on truck or me will be sore tomorrow.
