Recommendations for cam, throttle body, headers, other stuff.
 

As the title suggests, i'm needed suggestions for my next round of parts. It obviously goes without saying that i'm leaving the factory warranty far behind. I run quarter miles, so i'm probably bound to blow this thing up eventually anyway. =)

Right now (and this is subject to change of course), i'm leaning towards a 586 cam, American Racing Headers, and either an 85 or 90mm throttle body. My first question would be if these are good choices, and if there are better choices than these. My second question would be what other parts i should consider upgrading along-side these parts so i dont blow my engine?

Also, would anyone have any ballpark idea of what kind of HP/torque gains i would expect from these parts? (and if you're feeling saucy, how about these parts + what i already have, in hp/torque?).

I'm on my way to a supercharger next year. But these items, among others, are first. Thanks for the input guys!

Some of the options your mentioning will give you some gain in your peak numbers, but will sacrifice low and mid range torque for the top end. Not exactly what you want with our 5000+lbs trucks, unless your building a race truck.

Your likely not going to gain any significant power with your mods listed above, more just change your power characteristics. Better off to save your money, and wait for F/I. Magnuson should be releasing a root style blower soon for our Hemi's. That should give you a big boost in HP and torque through out the rev range.

By race truck, what are you referring to exactly? I did mention i was racing quarter miles.

What other parts should i consider that i didnt mention in the first post?

I did the mopar intake and exhaust si to dual out and have lost some bottom end but picked up mid to top end power. I also added the 85 mm throttle body and it helped a bit on the low end loss. To use the full potential of a 90 mm throttle body you need to have alot more serious horse power then you would get from bolt-ons.

Right, right. I'm not an auto expert by any stretch of the imagination, so i'm going with the upgrades i've seen other people do. What other parts should i be putting on here to increase performance? Again, the supercharger is coming, but not till next year. In the meantime i'm upgrading everything else i can, i just need suggestions.

A tuner, intake and exhaust alone will put you north of 440HP. I don't know how much a cam or heads will add but I am sure they will get you over 450-460 easy. Don't forget those 4.56 gears :icon_steer:

As it shows in my sig, i already have a K&N intake, Superchips cortex, and a jet 180 thermostat. My truck came with 3.55's, which i'll keep for now, since they are versatile.

I'd much rather have 450 flywheel horsepower than 450 crank horsepower ;)

But yeah, need more parts suggestions.

You mean Rear Wheel Horse Power? The flywheel, if we had one, would be bolted right to the crank.

I suppose i do. Guess i've watched too much speed channel lately.

Still need suggestions.

LOL, no worries, I am pretty adicted to that channel myself.

Supercharger?

Supercharger's coming next year. The unit i want cost 4k new, so i'm holding off on it for now.

Meanwhile, I read many mopar enthusiasts upgrade pistons and things like that, but i have no idea what i'm looking for parts-wise.

The cam you suggested (and thank you for doing so) has a less aggressive lift than what i was originally considering.

If i went with shortys to compensate for low-end, how are they going to be doing at ~100mph when i fly through the trap? I dont want to sacrifice a lot of high-end power just so i'll save a second on my zero to sixty time if it's going to add more time to my quarter mile.

What kind/brand springs/valves are you recommending? Any suggestions?

I didnt even really think about how MDS plays into all this. (why two heads are better than one). Am i going to have to leave it behind for good? And why would i need to buy a Diablo tuner when i already have a SC Cortex? And what is a CMR tune?

Well, I guess you could go longtube, with a torque convertor. I have the Mopar Headers (no longer in production) which were actually designed more as a midtube, which in returned would not throw a O2 code at the rear (not that it mattered to me anyways). I don't believe you'll sacrifice much high-end with an aggressive cam (more lift) running shorties. Any Comp Cam series besides the 260, will require a MDS delete (268, and 273 series). Your motor will run really rough without the MDS delete. Most guys I know that run the 273, usually have modified heads installed to allow for more lift.

I installed the 6.1 spring valves, and pushrods (my Charger), and I know of couple guys that are running the 273 cam with the same springs and rods. Running the 5.7 setup could be fatal, the springs/rods have less strength. If you can't disable the the MDS with your Cortex, at this point when swapping your valve springs/rods, you could always install the MDS lifters, to disable your MDS.

I'm not familiar with the SC Cortex... Does it have an option to disable the MDS? Also are you able to write a custom tune with the Cortex (aka CMR tune)?

For record, posting in all bold is less-desirable to read. Just saying.

I can disable MDS on my Cortex, yes.

As far as MDS is concerned though, for the total number of parts involved (thus money), wouldnt i be better off just going without it?

I saw Stacey David talking about adding a Magnacharger Supercharger on an 09 Ram on Gearz. If memory serves, it was supposed to add 130 RWHP.

If you can disable MDS through your Cortex, then don’t even bother with installing lifters, but if you're going with a more aggressive cam (more lift), unless it’s something less then what the 260 CC is rated at, I would certainly be replacing your push rods, and springs, at the very minimum.

Sorry about the bold, but that’s just the way I roll. I also use italics, nothing new for me though, it’s like that with all my forums I subscribe too.

That's pretty slick!
