Here's one for you, just to tickle your brain pan.

U20 head on an R16 block?

Thats a neat idea, but you are trying to put a overhead cam head on a pushrod block. In effect, you are trying to build a U16 (the engine doesn't exsist) but that would be what you would have. The U20 started life as a pushrod engine, was stroked, changed, and eventually you have a U20. I doubt an L series would bolt up either. The push rods are the issue.

See ya,

With enough money, any combination is possible. The question is why? U-20 blocks are not made of unobtanium - the timing parts are....
