Hi Dan,
You are correct, it is a 1968 side-oiler block taken from a Chris Craft. It is now a hydraulic roller motor. I used the original crank and connecting rods, so it is not stroked. Bored to 4.25 so displacement is 429 cu in. Heads and intake are Edelbrock Performer RPM. The builder put different valve springs in - anyone want a new set of Edelbrock valve springs? The cam sheet is below.
Regards,
Kevin
