400 into 65 valiant

Yes, I expect exhaust clearance to be an issue so I will definitely take that into consideration.

The incline is taken with the car on stands, level as far as I can determine. It’s not easy to find a level surface I’m the car. I’ve used the top of the door side, the bottom of the window opening.

I did think of something, I will try to determine the side to side offset of the trans cross member bolt hole for the trans mount tomorrow.

One other issue with putting it that far to the pass side is centerlink/idler arm clearance to the oil pan. Mine comes VERY close at full lock. You may want to bolt up the steering linkage to make sure it clears

Honestly, I would just bolt the trans up, whatever manifolds/headers you intend to run, and steering linkage, and lock the engine in wherever it clears everything. Height-wise, put it as low as you can without having clearance issues with the centerlink/idler arm. Done and done

***EDIT*** - Also, make sure you bolt up an oil pump. Mine comes pretty close the DS K-member.
