I have been thinking about this motor since I first heard of it several months ago. The problems I see with it are that it is not a marine motor. You have to pay for a carb and distributor you can't use.. If you have salt water in the motor, you can't use the head gaskets at all. I would be leary about the heads themselves unless you can flush it out everytime you use it. The other question I have is regarding the cam profile. The listing says 632/632 lift, 254/264 duration @ .050 but what about the lobe seperation and centerline? I have a friend who works at a GM dealer, I just talked to him today about attemtping to find out more information. I will post it when and if I get it..
What do you guys think?
