"I also posted re firing order

"I also posted re firing order on this engine. Basic facts are, A machine shop just long blocked my mid 60's 413 but used a 440 block because they could not find a 413. They used the old crank and cam shafts and heads. I have run the engine obout 15 minutes on 5 or less cylinders and accumulated what I estimate to be 2 quarts of water in the oil pan based on elevation on dip stick. She is raw water cooled. I have rebuilt and installed many boat engines but this is my first Chrysler in a lot of years. Feel free to comment / advise my skin is quite thick. Note, old block changed due to freezr cracks in block and water in oil. Machine shop claims they magnafluxed the heads prior to rebuild."
 
"Damn! Better start by yankin

"Damn! Better start by yanking the heads and taking a look at the head gaskets.

Did you reuse the intake manifold? Another location for a leak there, so check the gasket fit and port matching carefuly as you pull it.
