Dogwalker, an old WGer from Italy, seemed to know something about it. He said they rated it at 63 horsepower, and cruised it at 5500 rpm. Now you know as much as I do, Tom. :smiley:

Veglia or real? :grin:

Remind me what differed between the Aero and the 4V small block? Same displacement? Assuming it’s a different (and more reliable) head design? Crank and cam difference?

750 instead of 650. Hemi heads with big valves. It was fuel injected and ignition was by the early computer. Of course the cam was different, too. I don't know about the crank.. didn't have to go in that far to change it all over. Don't know about compression ratio either. After minor teething problems, it *has* been super reliable over the years, as I expected.. and my butt dyno says it will still out run the modern small blocks. :evil: Why they didn't build the Ippogriffo in the 90s confounds me.
