I have seen some of there stuff. I have also seen Arrington, XV motorsports, HHP racing. They all look good. If anyone has any feedback on what they have. Thanks

How are we supposed to suggest a cam/head combo when we don't even know what you want to do with the truck? 1/4 mile, 1/8 mile, street king, highway racer, towing, offroad, etc.

My guess is a streetable 1/4mile king......lol
Isn't that what most guys want?

I'd actually love to get just a towing cam to add to my low end along with some 4:56's.
I think the Ram would be a total beast with those 2 combo's and relatively cheap if I do the work myself.

I did hear that the ported 5.7L heads flow as good as the ported 6.1L heads and have much better low end than the 6.1's or have I heard wrong? So based on that, the ported 5.7L heads will be much better for a street truck than 6.1's will. i think Sherdaon's websits had stated the flow specs along with perf. specs????? cannot remember. I'mma gonnna go check'em out...hheheheheee

Dog, as you know, I have a torque cam. Low end torque/towing/rv cams don't really benefit from heads. My cam is basically a modified sidewinder design. I would see very little gain from heads simply because it just doesn't rev high enough to benefit from increased airflow.

Just throwing that out there.

That's why I would do just the cam and gears if it were me. I was explaining the heads for the other guy....lol

I swear they said the ported 5.7L heads will not drain low end but only improve it. I think that's how Chrysler got some extra ponies out of the '09's??????
I love how manufacturers use aftermarket companies to improve upon their own products...lmao

Either way....I don't have $3k to dump into heads!
Here's a link for specs

Rubber, what cam u got?
U get on the dyno? do you have a custom or canned tune? MDS or non-mds lifters?

[RubberFrog]

It's not so much whether a set of heads will flow more air. The real question is do a set of heads flow enough air for a given cam. In the case of a lowend torque cam, stock heads already flow more air than the cam can move. The real bottle necks are at the throttle body and the exhaust. This is where a ported tb and a set od headers can really help.

Mind you, I am talking specifically about low end torque cams and not cams in general.

I have a custom grind inertia cam. It has a little more torque than a sidewinder. I was running it on a diablo tune, but I am currently running the SC beta tune. I still have the mds lifters, but they are disabled with the tuner. The only downside is that the mds lifters are noisy.
