Hi Guys
The engine on ebay belongs to me.....Jim Green has nothing to do with this motor, but I can tell you that the guy who honed the cylinders used to be the shop foreman at Jim Greens but that was way back in the funny car days. Ron Moses is one of the best engine machinist I know.
Compression ratio is up there....11.5 to 12 to 1 Those small chamber edelbrocks have had a lot of grinding done to them and they ain't that small anymore
