I actually picked up a 20/22r in a trade awhile back and stuck it in my 78 street truck. It was fun till something came apart inside. I picked up another 22r bottom end to rebuild and i'll toss that 20r head back on with oversized valves, double springs, new rockers and a 292 cam from delta cams. Should be fun and cheap, the engine came with a 45DCOE sidedraft a 4 to 1 header and a full MSD ignition too. Eventually the truck will get a 3rz but for now I'm keeping everything old school.
I can understand why people build these hybrid engines now. What a hoot that little truck was even with a sissylala 252 comp cam.
