I have a 1969 playmate with a 455 olds and a berkley jet. I bought the boat in October and used it 4 or 5 times. It ran great and got up on plane just fine even with its little 2 barrel carb and the old points ignition.
While winterizing it I found a large weld on the block. I am guessing that it had some water in it that froze at some point in its life. It stays cool and doesn't leak so I am not very concerned.
Also, I found two plug wires that had no metal clip from the wire to the plug. I pulled the wires all the way off and started the boat. It sounded the same as with the wires connected so I assume that they were not firing.
This is my first olds and my first odd fire engine so I had no idea how it should sound. Even with the two plug wires off it idles smoothly and revs evenly.
Getting nervous I did a compression check and got:
3-160 not firing
4-145 not firing
I want to get this boat running well and very reliably. I got a HEI distributor with the boat. I was thinking of getting a aluminum intake so I could put a 4 barrel carb on it and I have read a lot of good stuff about the edelbrock heads. A more modern cam would also be in the plan.
Now to my question. Is this block worth working with? If not where can you get a decently built (cheap) short block or long block? I have not hand much luck finding any. They all seem to be 650hp and cost around $11000.
I am by no means a machinist and would barely qualify as a half assed mechanic so rebuilding my own engine would not be a good idea but I can do about everything from a short block on up excluding valves.
Any ideas would be helpful. And for those with a little too much stress in your lives flame away.
