I talked to the engine builder today. He did not have the cam card, because he said he gave to owner. He did say it was 260-280ish duration with the 660/640 lift. Said it was an Erson billet cam with the Morel lifters. and matching Erson springs. Said it a solid set-up that would live on the street with proper maintenance. Said it was actually built to drive on street, with in reason.
