Also this motor only has about 2,000 miles on it. This was done during the rebuild 350 .030 over,4 bolt main, pop-up high compression pistons ( I think 11:1), Torque Cam, Z28 valve springs, High volume oil pump, Heads have been milled, Factory Corvette intake, 780 cfm carb., 3500 stahl converter. 3 angle valve job.

Not sure of that will help any but just throwing it out there
