Would a 77 mdl. mtr. home have a 318 or a 360? And how can you tell the difference? All I could see was the casting date.

I thought the numbers were cast in them big numbers with rest of number. I believe the 318 would have that little 2 barrel and the 360's got that bigger one.

look on the DR front of the block at the top right below the head gasket junction & there'll be a very small stamped number "318 or 360". You might have to wire brush it to make it out. There's also large casting numbers on one side of the block (I forget which side) that'll have either 318 or 360 unmistakeably in the sequence (might be DR side). EDIT not sure now many 318's are cast cranks but you cant mistake the 360 offset weight dampener

95% sure it'll be a 360, I have never seen a 318 in a motorhome. It would be a real pig if it was.

Motorhome 360s have exhaust valve rotators to help the exhaust valves cool and stay clean. Motorhome engines are worked hard and usually have cracked heads and exhaust manifolds from the heat and hard work they had to endure.

Not real desirable to me. I've rebuilt 2 360s, both had 2 barrels, one in a motorhome and another in a HD work van.

I have seen several 72-76 vintage homes with the 318, Believe it or not they did it and they did the job to one degree or another. The numbers will tell the story,

HMM on another note, in 30 years will there be a premium for a MATCHING NUMBERS Winnebago ??? LOL Probably not but if BJ is still around, MAYBE LOLA

I was trying to ID it for a friend. I don't know my small blocks very well,can tell one from a Big block and that's about it.He wanted $700.00 for the whole thing. It was running and driving but had everything removed except dash and drivers seat.I'm thinking that was too much. Thanks for the replies.

I find motor homes in the junkyard all the time. I have seen both 318's and 360's. as said above if it has the big 2bbl. it will be a 360 and the # will be cats into the drivers side of the block. $600 is a bit much for a motor and trans(318 or 360)

I figured maybe $300 to $350 for the mtr. and trans. It had 65000 showing but he wanted to sell it all together. It looked to be a large Holley two barrel carb. Somebody had installed a set of hedman headers. Didn't smoke and fired right up.

You got it right Rapid, the numbers are cast into the block as embossed numbers on the drivers side. The 318's came with and W/O cast cranks but were always a internal balance.

good timing on that as I have a JY 5.2 mag long block on a stand & I was wondering about the balance. couldn't pass it up for $75 (I tossed the beer keg intake etc)

A friend tried to give me a good running 440/727 from a 77 motor home, but I had to take the whole rig, I turned him down because the hassle of getting rid of a motorhome is bigger than the value of the engine/trans ESPECIALLY a SB been there done that

I am not causing global warming, I am just trying to hold off a impending Ice Age!
