Very cool, the 320EFI was around the same time as well. I think that was a 350 too.

Have to check in on this one, my 22 Classic had a T300 also. I sold the engine to a buddy who stuffed it into an 18 Donzi. That engine was from what I have been able to glean over time was 300 at the prop, makes sense as it was a tad faster then the 454 330 hp BB. It has one of the nicest sounding cams!

Interesting drive in the pic. It's an Alpha SS, but it has side water inlets instead of the two inlet above the nose.
