6.0 in 67 C20 frame - motor mount setup?

[rcrahn]

Now that the 6.0/4L80E is home I am working on collecting the parts for the install in our 1967 C20. I ordered engine plates from street & performance. Nice pieces. Was told that I can use stock chevy mounts and the factory motor stands that the original 283 was on.
I decided to bolt it all up tonight while having a cold one and listening to the Sharks beat up on the Coyotes. I wanted to viualize how this will fit (or perhaps not) between the rails.
Here are some pictures.
My question to those more experienced. Will this setup really work? Or is it just going to be too tight? What about headers? I can see right away the factory logs are not going to fit. The AC compressor will be in the way. I expected that.
Any comments or input from those with a 67 who have installed a 5.3/5.7/6.0 gen III will be most appreciated.
