Morning everyone. Had a quick question and hopefully someone out there has some answers or knows someone whos gone this route. I have a 5.7 hemi and I have a 392 camshaft that I haven't installed yet. Does anyone know any official numbers coming from this set up yet? Just curious to hear news from this set up. Also I have a cai and exhaust but no tune yet.

Looking into doing this too next year. Buddy of mine told me that he did this to a 2012 challenger r/t and said the car gained 35rwhp from the 392 cam alone. No issues at all.

can you just drop this cam in or do you need to also do supporting mods such as valve springs?

Well, he told me you have to switch out the valve springs. He said he's done the cam swap to a few 09+ 5.7s and no complaints from any of his customers...:thup:

That is a 60 rwhp/40 rwtq peak that just takes off at 4000 rpms. I sent a PM to Brian as I would make the trip to Dallas to get this done. From the thread, the total cost for parts, install and tune is around $1,300. Like they said in the thread, those are better numbers than the stock 6.1.

The total cost for parts and labor is around $2100. Just got an email from Brian the tuner @ SNL Performance in Ft Worth. Arrington in Martinsville has also done a few of these mods.

The cost varies as to the type of springs and rods you want installed. This is a high end estimate.

There are plenty of shops around the country that has done this swap. You should look around.

I'd love to do this mod in the future. I know you can pick up a new 392 cam for less than $100. How do you go about actually installing a cam in one of these motors seeing how little work space you have in front of the engine while it's in the car?

May I be let in on this secret? I'd like to one day try this 392 cam mod as it actually seems like a practical upgrade.

The trick (Not sure if that is what he meant) is in the tune. The tune takes time to get right. It can be done via email with data logging but my personal choice is on the dyno. For the cam install, here are two sites, one for the truck hemi and one for a charger. Both are pretty much the same and if you have the right tools, are a decent mechanic, and the time, it is not that hard.

For a 40-60hp gain on the new hemi's, IMO the 392 stock cam install is the best bang for the buck!

But I want to know how you go about installing the cam with the engine still being in the car, with the very limited amount of workspace there is in front of the motor... Also, could anyone possibly tell me who does tuning in or around lower NY?

That's it? Just the radiator? The AC condenser can stay?

Alright. That doesn't seem like too much work. That's going to be the next performance mod after I do headers.
