I have a 1970 Slickcraft boat that has a chevy 307, motor is marked as a OMC...
Wondering if this motor would be the same as the high performance motor?

Sorry it was a few years back on the 427 about the time I purchased the LS7's. They were before I had a cell phone with a camera. lol I do have a pic of where one of those wound up.

I know where Chevy found the extra 45 HP in these 307's An nice set of 186 heads. The engine casting dates are June and July of 1970.
