Wow, it's been really HOT~ 106 in my tall garage! I did what I could, today played with my new to me slant six. I wanted to get it mounted on my engine stand, and I did.
Sweet! Looks like an '81-up hydraulic lifter slant 6?! I used to have one of those and here are a few tips: No one makes these valve covers (different shape/ bolt pattern), so be sure to not overtorque them. When getting valve cover gaskets and spark plugs (no spark plug tubes!) tell the store it's a 1983 Dodge D150. I was told you could bolt on a pre-72 (?!) head and still use the hydraulic lifters/ rockers. The only advantage would be to make it look period correct and you could get new valve covers for it.
