Would it be more efficient to use 2 GMC 305's or 2 Chevy 292's?

Maybe some of you are already aware of this but in case not - check this out:

Take 2 LSX blocks, cut the last two cylinders off opposing ends, weld together. Sounds simple....

I will look, thanks.

I ran across a GMC 702 V12 years ago, it used to power a lift at a small ski site in the NW.

Not sure how a pair of 292s will make a V12...

The GMC V12 if I remember correctly looked like two V6s connected, but wasn't.
They were also used to run irrigation pumps.
There's a thread with one put in a 60-66 truck.

Maybe put 2 292's in a frame and use a pete jacobson type gears to run a huge flywheel.....
