I am in the process of building a 71 429 SCJ for my jet boat. This engine has D00E R heads and D0VE A block (4-bolt main) along with the stock 429 crank. I am looking at using Sealed Power flat-tops and crane Extreme marine came #XM278H12 cam with magnum roller tip rockers.
What is the recommended piston to cylinder clearance for use on a jet. My cooling system has a pressure regulator set for 15# and I am using a gate valve to regulate volume.
Thanks for any advice as I don't want to screw up this engine for obvious reasons.
Let me know ford guys.
