I’m on board if they’re bored and stroked to 454 with ported heads and tunnel rams

Theyll be more efficient than bbc blower motors for sure. But I wouldn’t think they’d be more efficient than an injected big block. They may have a better chamber, but that would be a minor improvement. If you’re talking apples to apples NA motors.

I think we once again missed the point. That 468 blower motor is not something I an competing against. Just a reference to judge against as for accuracy of the dyno I ran on. Thats it. If I wanted to compete with a blower motor than I would compete by either turbo or supercharger/ procharger. Not the case. Its just a reference

iron. My block is like 90lb heavier than aluminum ls. Mine all in with exhaust front accessories everything will be in the 600lb range. Exhaust minus risers are even aluminum. Oil cooler is not mounted on engine. Everything on ls is smaller. Crank rods pistons valves heads. It all adds up. And then add though beautiful, but heavy headers, efi intake fuel rails, ecu, distributor etc.

I’m all for you doing whatever you want to your boat. I feel kinda bad for this second guy you convinced to do the same with all of these exaggerations though.

Would be awesome but out of room for growth. Big power though for sure. I kicked around waiting a tear and doing this with lsx block but cost was significant
