Thank you all for the help. In my initial post, I stated I was finishing a rebuild. The gentleman I got the engine from had it rebuilt years back and had the following done;
"As best as I remember, valve job, valve train, and lifters....bored 30 or 60 over with new pistons. Crank was turned +30 with new main and Rod bearings. I think I kept stock cam. And as I mentioned alum flywheel new clutch and pressure plate."
He also stated the engine was rebuilt at a stock car racing shop and he was running a Holley 500 prior to rebuild. We opened it up and he was spot on with the rebuild. So all I added was the headers and carb. I figured the edelbrock 600 would give it a kick. I will keep everyone posted. Oh and the gentleman who had this engine was a good man. Really honest and open. He opened his home and shop to me (a complete stranger) so we can inspect the engine before buying.
