RV Cam - Improving Torque?

[m1ndless]

Hmmm. I might just call some Cam companys and see what they reccomend for my truck and specific needs.

I get paid on friday, I plan on spedning 80% of it on parts, granted I only get 1k a paycheck, I wanna spend around 700, so I will look for some headers, cam, and exhaust, and get my new frotn suspension lift instead and get off these damn blocks!

absolutly call the cam companies, i have personally used comp cam, and was very pleased, until i wanted a custom grind done up and things got confusing for some reason.

but i also agree, a lower rpm cam, like the xtreme lineup will have a very flat torque curve that will extend probly out to around 4000 rpms before starting to drop off, and i dont see the point of having a truck that will wind up more than that. but thats just me.

im sorry im retarded but is an "RV" a cam just a cam from an RV camper? or a different style of cam?

it is a camshaft with a grind that is meant for low end torque. Its meant for installation in RVs and tow vehicles to help where they need it.

Which is why some people here don't notice much (if any) improvement in performance. Most K5's don't do much heavy towing. In my heavier trucks the RV cams were noted not for the power gained so much as for the power NOT LOST.

From what I understand the term "RV" really has no specific characteristics other than that it is a general term used for a low RPM high torque cam. I'd call Comp Cams and talk to their tech and just forget about the "RV" term. I am finishing up a 383 stroker and I used this cam: XE262H

According to Desktop Dyno and the owner of the machine shop that did my work, who has built this exact same engine many times and dyno tested it, my engine should produce @ 450lbs/ft. of TQ and right at 380-400 HP. Peak TQ is at 2500 RPM. That's right where my truck runs when towing my camper which is pretty much what I was shooting for.

Hmm. I will give comp cams a call tomorrow. How much did it run you for a cam? Arent they only like 50-100 bucks? Are they hard to install? Something I can do or have my mechanic do it for me?

$100 at a minimum. Hard to install? Not exactly a walk in the park. wouldn't be a bad idea to replace lifters(they sort of work with the camshaft, just throwing a new cam with the same lifters isn't extremely advisable) and a new timing chain on at the same time.

Whats your mechanical skill?

Have to remove the intake, valve covers, water pump, oil pan has to be lowered, balancer off, timing cover off, timing set off, pushrods and lifters out, oh distributor too, and then finally the camshaft. Which to do in the vehicle means the radiator and possibly the core support has to go.

See real easy.....

I almost set my truck on fire at one point just doing my crossover. (Actually, I wanted to torch the SOB a couple of times - but that's another story) I have an aluminum intake that I don't want to put on b/c of the tear down and install work to do that...

If you're planning on wheeling the trails the AZ CK5 gang runs, then make sure the motor keeps running at steep angles, and otherwise leave it alone. You're probably better off focusing on suspension, gearing, and tires.

if it has a mechanical fuel pump put that on the list to.
