I wish i knew something about engine design to know the difficulties of designing a custom engine block and crank for those 'busa heads.
I don't know if you have heard of the Cizeta Moroder V16T. But they made a V16 from 2 old lambo v8's (I think Jalpa engine?). The resulting engine has 4 lambo heads and 8 camshafts on a common block and crank.
This practice of combining multiple engines has been around for a very long time.
Below you'll see the pictures of a 30 cylinder Tank Engine - No KIDDING!!! Fully rebuilt by my pals at Carriage House Custom Automotive. It's a 1942 Sherman Tank - Multibank 30 Cylinder using 5 Dodge 251cid 6 cylinders. We're trying to figure out how to get her mounted up on the Dyno...




Now - which RCR should this monster go into?
Err... Say Fran - you're not into Tanks are you??
