360 out of a 1977 RV

Intake and,v covers off and she's real clean. There is orange and green paint on the springs reen paint on some of the rockers. Can anyone tell me what it means?
it means there's been some head work.
I personally am not a big fan of RV motors. Most are over taxed : lets take this big @$$ RV and go to the mountains and here's a great idea - let's pull the boat along too! Now before we leave lets pack enough clothes, food, and firewood for the six of us for the nine days we'll be gone. Oh yeah, before we get on the highway lets fill both 40 gallon tanks and the 20 propane tank and while we're here lets just go a head and fill the 20 gallon boat tank. "Honey I'm going to run in the store and grab a 20lb bag of charcoal for the BBQ, I'll be right back". Well that was a great trip and we almost didn't make it over a couple of those mountains, but we groun out first gear for a half hour and made it !! Well we'll see how long it sets (a year? Two?? Three???) Before we touch you again !?? Ask me how I know . ...
