Interesting, thanks for bringing it back.
I thought we discussed this before and basically came to the conclusion that these engines aren't magic - they are a Gen III with decent heads, intake, and fuel system, that are dyno'd accessory less, on a friendly dyno. I don't think their results are anything we couldn't duplicate?
Good point about the extra timing. They can probably be a little more creative with the cam profile too.they would have to turn the water pump???
& they can do more with the timin because of the extra coolin a marine engine has availible to it
I believe it's a closed cooling system but either way they are still using cool water to extract heat through conduction which is better than trying to cool it through air.they would have to turn the water pump??? & they can do more with the timin because of the extra coolin a marine engine has availible to it

Boat motors also have tighter ring gaps and typically cams that are designed more for maximum hp at high RPM and less concentration on lower RPM drive ability. That combined with cooler running temps and less chance of detonation make it easier to get bigger numbers out of them.
I didn't know that about the ring gaps. I actually thought the Illmor's used factory rotating assembly's.
The marine grinds that I have looked at for old school V8's weren't peaky at all. They were big torque cams with broad power bands.
