Anyone know a part number for a freeze plug kit for the engine in the thread title. Was not sure if a GM cross reference would work. Thanks in advance- Geoff

Go to any auto parts store and give them the year and GM 5.0 and they should be able to find Brass or Stainless Steal plugs

Should also be able to find them on line at a place like Summitt Racing or Rockauto

Napa keeps core plug kits in stock. marine use brass or stainless. cars and trucks use coated tin

Melling MPE-100BR is for small block chevies from 1957-2014

however if they were pushed out by not winterizing, the block cracked

Agree with post #4.----If pushed out by cold weather then inspection is required.-----They are " core plugs "----And somehow they began to be called freeze plugs.

Remember, the block water jacket should hold 15psi.

the points of failure if it froze will be both exhaust manifolds will have a crack on either the outboard or inboard side, just above teh centerline of the exhaust ports, and both waterjackets will have cracked on the inside of the cam valley, and the heads will crack around the exhaust valve bowls

Ok. I finally got back to cranking the boat and unfortunately discovered that water was leaking along a crack along the block on both port and starboard. Pictures attached.
I think my options are 1 to replace the engine block, 2 get a complete drop-in replacement or 3 see if I can sell it for anything along with the trailer. I am guessing from the length of the separation on the photos- 5-6 inches that a modified repair is probably not an option.

Anyhow just curious to hear from those who have undergone an engine replacement. I am mechanically minded and capable, but would need some direction if I were to replace the engine block. Where to start with engine search would be appreciated as well. Thanks in advance- Geoff
