It is possible, but you have to know what you're doing and how to tune it correctly. We've had one SC Riv engine go "boom" running an L36 block.

More modern engines use direct fuel injection, which allows boost + high compression more easily. But it can be done with the SC 3800, just can't run as much boost.

I think there is more potential HP on tap because the higher compression requires less boost, keeping the supercharger spinning in a more efficient (lower) RPM range. You can build a normal L67 to be just as powerful, using more boost and hotter timing.

Doesnt Codith have the lower L26? Not sure if that's higher compression but it's the N/A engine, right?

Yes, L27 is the Series I 3800 N/A, L36 is the Series II N/A. I'm not sure if there's a preference for mating ether block to the L67 heads, but they are different blocks. Maybe turtle can educate us on the pros and cons of each.
