Default Twin LS1 powerplant

I've been tossing around the idea of building a twin LS powerplant. Most likely twin 5.3's for cost efficiency. I am at a loss as to how to connect the two engines mechanically. Is there a coupling available to tie the two cranks together? I have seen drag cars of the past running twin v-8's so I know it can be done. If anyone can point me in the right direction I would really appreciate it, thank you.

I think you have to make a stub shaft for the front of one and another for the rear of the other, then use an industrial coupling to connect them.

Inline or side by side mounting?

This guy is using a TR6060 driveshaft coupler with some custom work for an inline setup.
I think I have the rubber coupler and the driveshaft side if you decide to go that direction.

Run a pair of LS4s with transmission. An engine/trans for each axle.

Sounds good, but then you'd have TWO blown trannies....
