I'm just curious as to what everyone thinks of the 210x cam it's a bit bigger then the Hughes cam I have now and I want a little more top end power. I do use the truck to tow and haul stuff so I need some low end torque but I Also want top end. I also have the stock heads that I eventually plan to upgrade but will the 210x cam work ok with stock heads and the kegger intake until I can upgrade them? I'm just tossing around the idea of using this cam and want some opinions I basically want to run the largest cam I can without sacrificing the trucks use as 4x4 pickup truck. I have an 07 dodge 2500 to tow a 30ft fifth wheel and flatbed trailer with but I do use my 96 ram to tow up to about 6500lbs on the flatbed now and then I want to still be able to use it for doing that

 

To get the most out of it, you would need a custom tune. (or, at least, a better tune than stock....) Also, you cannot use stock valve springs, that cam exceeds max lift for stock heads. Power band starts pretty high for that too.... 2600 RPM? I don't think that would make for a good towing cam, unless you coupled it with a high stall converter as well....... (which really wouldn't be that great of an idea either......)

 

I thought KRC state in their website that it would work with stock valve train?

 

Yes it did. Stock sized valves/heads with stiffer springs. 210x made more low end torque then the comp cams 604 which has the same duro/lift as the 210 and 210x. The 210x is ground on a tighter LSA 110+4 vs 112+4 given it lower RPM torque along with more peak. According to spec's the 210x will produce more torque then the hughes cam on a 114.

 

You will need gears with this cam...I am running 4.56

 

Stock cam need's gear's. Plus your running large valve heads with a small cam.

 

Advertised lift on that cam is .512..... from what I have read, max lift on the stock springs is .480. Also, as stated on the website, (on the same blurb where it says it will work with the stock valvetrain......) power band is 2600-5500...... That doesn't sound like a cam that will give you much in the way of low end torque to me.....

 

Typical Hughes bull****...That cam won't work on a stock valve train...The stock valve train is barely good enough for a stock cam.

 

KRC used to sell a 206X cam. That was the one they recommended for towing, until Bill had a different cam made specifically for torque in his durango.

210x was not recommended for towing. When KRC said that their cams could be used with the stock valve train, they were referring to being able to reuse the stock rocker arms and pushrods. They did recommend springs for any cam over .480 lift.

Most Hughes cams are ground from a stock cam core. You'll get the same LSA, intake centerline, and basic lobe profile as stock. The way they increase lift is by grinding down the base circle. Any time you change the base circle, you'll need new pushrods.

 

Sorry I didn't already mention this but I have upgraded to Hughes valve springs rated for .600 lift and upgraded the retainers. I also have 4.11 gears on 31inch tires. And I have the Hughes shaft mounted adjustable roller rockers so the different base circle of the cam is not a problem for me. I'm still kind of interested in the cam but the fact that it doesent really kick in until 2600rpm is kind of scary for towing. Would the hughes air gap intake give me some more top end without sacrificing all my low end torque?
