I don't see anywhere on their website about ported/polished heads for out motors. Is this one of the things we're waiting for them to release?

I'm trying to do my research comparing all the one's offered for out motors, specifically our trucks. Trying to get the lingo down as well. I looked in the Indy catalog, and wasn't sure if I was understanding it right. Coming slowly though, lol.

Arrington does, yes. Not sure why there isn't any info on this. Hopefully, they'll hop in here and let us know about the various 5.7/6.1 offerings as I'm looking to do the same on the Magnum.

Right on, would be good to know. To some it may be a no brainer, but there are a few options out there, and I always study twice before I buy. Even if I don't buy, just for future referance in case I do.

Are you wanting to do a 5.7 head or go with the 6.1 port-matched to the 5.7 intake? They literally have the ability to do anything, I think they're looking to see what most consumers are looking for. CNC, custom porting, performance castings, etc.

I personally would like to see all new castings. I think the 5.7 head is limited and I don't think you can get the 6.1 to equal the cc size of the 5.7 and still line up with the intake (could be wrong).

Well in a perfect world, I would say yer right about making a new casting. Frankly, I don't know what I want, I'm still researching. My eyes are probably bigger than my stomach.

I'd like to eventually go with a 6.1 intake manifold, so that would mean going with 6.1 heads would be the best bet. But obviously, I don't HAVE a set of 6.1 heads laying around. Kind of a dilema.

I guess I'm thinking I can go with 5.7 heads rather than going all out at this time. I suppose I could always sell P&P 5.7 heads and sell them later go get 6.1 heads when I have $$ and time for a 6.1 intake.

But then again, heh... (here's my mind thinking again, so I apologize), I've seen 6.1 crate motors go for around $5k, specifically from a dealership here in my own town even! All the money I'm putting into a 5.7, I'm thinking why bother with it, and just invest in a 6.1 that's already at least a little more powerful, but a better base line.

I just don't have cash flowing in fast enough dag nabbit! Brick wall I'm already being made fun of at HTC for the idea's my mind goes through, lol.

Just do what I do: knock over a liquor store.Whistle

I think I'd rather keep 5.7 heads, but I don't know how much horsepower they can support as compared to a well-worked 6.1 head. I think we'll be seeing more options for 5.7 intakes soon, too. The 5.7 heads on the Arrington 370 I have made 490hp with a stock truck intake, so I think it's safe to say they'll support at least 500.

Y'know, on any other truck, modifying is easy. Intake, exhaust, MAYbe a cam or so and headers. Then you can spend all yer money on makin' it look good.

HEMI trucks: well they're supposed to be fast, and easily made to make some good power, and have fun with. It's just not cheap. So ya just gotta spend money on the motor, not cause it needs it, but because obviously, if ya bought a HEMI, yer a power junkie of some kind.... AND you have save for wheels, paint, body work, custom stuff, etc. It's not easy owning a HEMI truck. Boo hoo!

But boy is it fun!!! Applause

Sponsor? Pfft....I'm telling you man - liquor store!

I know what you mean about it ain't easy modding a Hemi. I've stripped my truck down and sold all my mods because I had made up my mind this was pointless - twice! But, now that the aftermarket is finaly catching on that LX and Ram owners are serious it's getting pretty fun and more gratifying. I just hope there are enough liquor stores for everyone.

I'm ready! I'm one to try and always do something right the first time. Problem is I'm not patient when it comes to waiting for the money flow, lol. Bad combo!

It would be nice to see a brand new head set for these engines with only 1 plug instead of two, so you could run the FAST coil packs or the MSD coil packs instead of the factory unit. What would be nicer still is a nice set of valve covers to mount them to....

But aren't we looking at 2 differant animals? The LX cars can afford the huge flow and ports but if I understand right the smaller 5.7 ports are better for establishing torque to get our heavy ass monsters running?

The 5.7 is the same in both vehicles, the intakes are different, and the cam, front timing cover, water pump, power steering unit, dampner. But the rest is the same....

What I meant was with that right up, the car intake makes more torque, flows better than the truck intake. But, on the stock set up the results are the same. I know the tuning has alot to do with it. So I feel that the testing in this article is flawed. What I would of like to see would take a stock LX, and swap out the 3 manifolds and then see!

With this test if you take the stock LX manifold I garuantee that you will NOT have 40 ft# more that the stocker

You and me both...along with the XL Motorsports intake, and the M1 intake...

If ya ever have a reason to put another injector in a TB or spacer, the LX manifold does not distribute the fuel as well as the truck manifold for equal A/F per cylinder.
