Hi there. I'm in a bit of a situation here. I have a 78 Fiberform 19 foot open bow PROJECT boat. As I was replacing the floor and floatation foam which I originally thought was the reason it was a project, I found the real reason. The original Chevy 350 block has a huge bulge and a number of cracks in it.
So as I see it, I have 3 options
1) If I'm so lucky, the cracks in the original block are external only, I can have them welded and rebuild the motor. With my luck, this is not an option.
2) Find an automotive donor 350 block and rebuild it for marine use using the internals of the original 350
3) I have an 305 from a 1983 Chevy truck. I could rebuild it for marine use using the internals from the original 350. If I go this route using the cam from the original 255 HP marine 350, anyone have any reasonable ideas what type of power the 305 would produce.
My intended use for boat is tubing, maybe a skier and definitely a fishing/swimming platform, nothing extravagant.
Thanks in advance for the advice
