When Choosing an aggressive grind cam please note that a custom program is mandatory for performance gain. Please take this into consideration when choosing your cams.
Unless tuning is available I personally would NOT recommend any grind greater then the H.O cams if you do not own or plan to run a custom SCT tune.
RUMOR that the cams in 2005 are H/O cams... NOT TRUE! There are completely different part numbers, the 2005 H/O shares the Standard cams as there is no H/O cam listing for 2005.
Here are the part numbers:
2002 H/O cams - 53x21412AD(RIGHT) 53x21411AD(LEFT)
1999-2007 53021160AE(Right) 53021159AE(LEFT)
2008-2009 53021983AA(LEFT/RIGHT)
Anyone who is saying the new Base 4.7L is the same as an H/O does NOT have reliable sources giving him his/her information.
1999-2007 4.7L cams are interchangeable.
2008-UP 4.7L cams will NOT fit older style heads. In 2008 the 4.7L received new IMPROVED heads and cams specific to the 2008-Up heads.
H/O cam's- What can I say, these ARE GREAT CAMS!
These cams are a direct bolt in and will net you approximately 20-25RWHP with no additional mods. Additional mods only add to the gains.
I had the H/O cams installed on my 5200lb Quad Cab Ram and was running 9.91 in the 1/8th with a Superchips program, Gibson headers, 4.56 gears, High Flow exhaust & ASP underdrive pulley.
206 Cam's - Tune is highly recommended! For best performance these cams Require an SCT tune or equivalent. Although they will run with your stock PCM... these 206 cams will not run as good as the H/O cams until you get a tune for them. At that point they will be able to edge out the H/O cams with slightly more HP UP TOP.
212 cam's - Tune is MANDATORY! These cams will cause all your engine tuning nightmares to come true without an SCT tune. A PCM FLASH is NOT recommended! Higher Compression Ratio should help and is recommended. I'm currently running these cams on my 2002 4.7L Quad Cab Ram and do NOT feel they are suited for such a heavy truck, I feel they would benefit a light weight DAKOTA with Standard transmission.
The 212 cams require an SCT tune with Data logger minimum.. If you cant tune for them you will run slower! I personally will NOT recommend these cams for anything over 4500lbs. Even then a 2800 stall converter (Or Standard Transmission are a must. As well as a Headers/intake/High flow exhaust system/70mm Throttle Body.
218 Cam's- CUSTOM Tune is MANDATORY! You will also need HIGHER compression ratio of 11:1+ Nitrous or Boost. 2800+ stall speed converter, 72MM throttle body, Headers, High Flow Exhaust/Induction system.
