hughes vs mopar performance

(Tell her to stop talking about me or raise my price! --- LOL! JOKING!!!!!!!!)

OK, SERIOUS biz now. Back on topic!

People trash the MP purple line up real fast, but, they do what they say they do and they do it well. There also a compromise between the more radical cam lines like an aggressive Hughes or Lunati cam but much more powerful than other lines of cams that everybody offers. The Purple cams were designed to meet the needs of the grass roots racer (AKA - No Money!) and make the power with little work needed to get the job done.

Notice how the lifts of the Purple cams are not big. But the duration's are. The cams work with stock heads (and MoPar even has springs for them.... ) with minor work. Bowl porting can get you very far.

Here's the thing about cams that you should look at when thinking about one for your engines performance.

First, know the RPM range your driving in and have the cam operate in this RPM band, the lower 1/4 of the cams intended range is about the cruise area. Not more than half though.

Know your heads flow ability. cfm wise. Where the flow stalls. There's no real point of lifting the valve above the stall point if your on the street driving around.

If you can take advantage of the most lift you can get in the duration your looking for (Driving RPM range) then, by all means, do so use all the lift you can. Lift has a direct impact on HP. But not a whole lot for street cars. MAX lifting the valves on a street engine seeing a lot of driving isn't needed. If anything, it's just more stress n the valve train. Go there (Lots of lift) if your looking to mow down the comp in the streets.

Then, your down to the cams centerline. 110 is the standard. A aggressive 340 or 360 can go to a 108 easy, 2 more degrees - 106 - if your on the track.
