Mark:
On my 2 previouis boats with the 5.8 Small Block Ford, I used these:  I purchased them from McMaster-Carr: https://www.mcmaster.com/products/petcocks/drainage-valves-5/ I had one for each side of the block and one for the U-Bend (J-Bend) in the raw water system. I also replaced the cast iron plugs with brass plugs at the ends of the exhaust manifolds/risers. JQ |

Question about this, if your installing drains on the rear of the exhaust manifolds,
I noticed quite a large build up of silt on the 79 behind those 1/2 drive plugs, granted maybe from lack of service being an orlando boat. How about routing the cooling hoses to the rear of the manifolds ? My thought is it will always flush silt out and pop the hose off for winterization, like to know if thats an option good or bad. |
