I have a 1956 Chev 2DR HT with a 1986 corvette engine. I would like to know if a LT5 would mount up. Also if a 700r4 transmission would bolt up

A LT5 will fit under the hood of your '56 Chevy.
Mounting it to a 700R4 might be a little more challenging, but probably not impossible. It's been done with 4L80/4L80LE, can't be too much different.
You will need a custom flex-plate made, but luckily there is a guy over at the ZR1 Forum who can help you out, his name is Pete, here's his web-site.

Good luck!!

AND, add the 4L60E to that list.

The engine mount configuration is akin to the LT1 configuration in C4. This is different than the L98. Spacing maybe the same but mounts are different.
