RV cam specs

Does anyone know the specs of a 350 RV cam?

If they are different dependent on brand or something, let me know...I'll just call the guys that I bought the cam from for the specs.

Also, what does RV stand for anyways?

RV=recreational vehicle

Anyways, yea that description of the cam is basically useless. I would call the guys you got it from and ask for numbers, thats what you need. Its probably not a very good cam for anything but a motorhome though from what I remember those cams being.

This guy I used to work with always told me how he was the first one to "hot rod" his camaro with an rv cam. I never thought it would be a great idea to stick one of those in a car, and there have to be better choices out there today.

and rv cam is designed for torque, depending on what you want to do with your motor that can be a good thing, my cam im putting in could be considered an rv cam, low duration high lift it'll make crap loads of torque from idle to 4000rpm which is what i want, im not planning on winding it past 5000rpm, so i dont need a large duration

It means mild cam , that term is used by the same people that use "3/4 race cam". As soon as you hear anyone use it disreguard anything else they have to say.

Anyways it can be Alot of different cams , so like Madmax said you should call them and get the info.

RV cams are basically useless, unless you have a RV. They're designed for heavy vehicles. Crap loads of off-idle torque. They usually are low duration too.

Some of the cam mfrs actually make cams specifically for RVs, to give them some torque and gas mileage. Usually they go for low duration and medium lift. Comp used to make some in their High Energy series, with like 240 to 252° duration. They make good tow truck cams too.

The .390"/.410" POS is the "929" cam, that GM used to put in everything from 283s in the 60s up to 350s and 400s in the 70s, that had 2-barrel carbs or otherwise was low perf. It sucks for any use I can think of.

Like everybody says, it's the opposite of what we usually look for in a cam. Get something else.

Most of us "old timers" would (and still) quietly laugh when someone used the terms "3/4 race" or "full race". Most of us never go into a race putting in only 3/4 effort. There are many such terms which quickly identify the uneducated, like "drag pipes", "full posi" etc.

Maybe they think a "3/4 race" cam only has twelve lobes... that would be a somewhat limiting factor.

Lets look at the term RV,"Recreational Vehicle."
Doesent anything besides a daily driver qualify as a recreational vehicle? You use it for recreation dont ya?
Most RV cams arent used for BIG A$$ motor homes mostly small truck aplications but if you think about it an basicly unmodified 3rd gen that operates from 800RPM-5500/6K would be a perfect candidate for an RV cam.
I used the MTC-1 RV cam "thats probably the one they sold you, very common" with my old 305 and it ripped *** very well!

I was at the local speed shop and noticed on the end of a Crane cam box it actually said 3/4 race cam, I just busted out laughing, and walked away

3/4 race cam, I want a full race cam.

Oh there's no doubting a RV cam can make an improvement in a non-RV application but it's not the cams intended application. My Dad bought a L69 and the previous owner installed a "RV" cam in it and my Dad stuffed it in his hot rod and he runs high 13's all day. There's no doubting that they perform it's just that......would you wear female's anti-perspirant?

Here's Comp Cam's definition of a RV cam: Serious low end towing power for motor homes or big trailers.

RPM range: 800-4200
duration: @ 0.050" 206/212
Lift w/ 1.5 rocker: .425/.440
LSA: 108*

Not a bad cam for your daily driver I guess, except it's been specifically designed for heavy vehicles and to generate serious low-end torque and nothing up top.
