Maybe "RV Cam" means a dash cam in a RV ????
And a cell phone is the phone in the cell when you go to jail....

Well if Billy Godbold says it you can pretty much take that **** to the bank. That guy is a genius.
To me, in the English definition, to "put a RV cam in something" means you take a camshaft out of an RV and put it in your Duster. Correct ??

You could. A 360 cam in your Teen would work fine.
Now THAT would truly be an RV cam. When somebody ask, I could say "I put a RV cam in it"
Stock 360 cam specs are all over the planet. Here's one:Now THAT would truly be an RV cam. When somebody ask, I could say "I put a RV cam in it"
The specs for a stock replacement “2bbl” cam are:
Clevite 229-1663
SAE duration 278/278, duration @.050 203/203, .410/.410, 109.5lsa.
SAE duration is .006 divided by the rocker ratio, so .004 in this case.
Factory cam specs are:
71-74:
252/256/32 .410"/.412"
75 and later:
252/252/33 .410"/.410"
According to Larry Shephard the best cam for fuel economy in a small block is the stock 360 cam....
I've run the 360 cam in 318, I liked it.
It doesn't matter what temperature a room is, it's always at room temperature...
I have a couple stock 360 cams in my stash for economy builds... I need to try one of them sometime...
Like asking for cold ice. Ice that's -15° is colder than ice that's 31°
I will say, putting a 360 2bbl intake/carb and a 360 cam in a 318 makes a punchy 318 and keeps it pulling decent.
How about a 360 cam in a small block with a 600 cfm carb??? Like a Holley 1850 series, that should run good also....
I think a 318 or 360 with true 9.0 - 9.4 compression, a stock 360 cam with a nice dual plane intake, Holley 600 vacuum secondary, and dual exhaust would be a nice street economy engine that you could take down the track occasionally and see if you could get 20 MPG with it on the highway...
That would be a dandy
I saw a video on youtube from a Yale thermodynamics professor deriving the efficiency of the otto cycle (the gasoline combustion engine) is directly related to compression...

I was like, get grandpa out of there and let some young buck drive that thing. Then...
Depends on who you ask.
This is the basic thing that was done many moons ago which is most effective when you start with the earlier 318’s from the 60’s with there higher compression starting points. Or any older engine for that matter.
The best tricks to make that stock OEM using equipped car were to kill the heads rod that edge in compression, 3 angle valve job (or a race valve job in todays standards.) and if you had enough money it was a port match and porting to gasket size on the heads and intake. Bigger valves if the wallet was thick enough. That was a lot of money in the 70’s. Aluminum heads were not available and the only upgrade for the small block back then was the W2 head. Very pricey back then.
Upgrading the cam was always part of that performance combination along with headers. This was always proven to be a very good street combination.
It’s much harder to get good results from low compression engines from the smog plus era. I’ve measured late ‘70’s 318 as low as 7.5-1. That’s Yak piss compression. If you could get to at least 8.5-1 or better, a small cam would work very well and still use 87 Octane.
My old Magnum’s ’79 360 was a fair performer with its stock long block and use of factory iron intake. The newer ‘00 - 5.9 is much more powerful. I do t know if I’d would get 20 mpg’s with it because I went from 2.76’s to 3.55’s & get about 17 now. It’s been a while. I also went from a 904 to a 727.
Some people just use terminology that they have heard from others without actually knowing what it means.
I had a '78 Trail Duster in for an emissions test and it was over the limit. The Service Advisor asked..."Does it have a cam in it?"
Of COURSE it does. It wouldn't run at all without a camshaft.
I knew what he meant but it was a weird way to ask if the engine had an aftermarket cam.

For sure. And I get the "RV Cam" terminology as I've heard it all my life as well, but it's kind of a loose term that really means nothing.
Any time I hear it, I’ll just think small cam size under 218@050
One time I tried to buy a cam for my 2 stroke Yamaha motorcycle. The man said they were on aisle 3 next to the radiator caps for Volkswagen Beetles.
