It sounds as it comes with a high price from broken or inferior parts...I hope its worth the trouble and expense...badazz car by the way!!!!
Thanks!
Just for my understanding what high price broken/inferior parts are you referring to?

1Badx - This might be a more appropriate forum to get the facts sorted out on using cast pistons with FI. Can you detail your exoeriences with the factory slugs - espevially the 6,1 - and superchargers....including any thoughts you may have on using a blow thru system? I have no personnal experience - but was pretty much put off the idea when I posted on the LX forums by people saying they wouldnt last - that the top ring land would fail.. I would only be considering around 7psi at max.....so interested to hear your opinion?

Okay- I have a question for you guys-
How much naturally aspirated power will the stock pistons and rods live with in a 6.4 liter engine?
Forged crank,
powdered rods, cast pistons
Just a WAG, but I could see where the piston to valve clearance issues, plus the extra strength built into stock stuff for warranty would keep you safe with all the bolt on goodies you can screw together. Headers, ported heads, manifold, tune, cam, the works. I would guess somewhere around 150 more hp.
You can get a good idea by researching who is going fast with bolt on parts in the LX forums, and who is driving over some of their parts. The latter have found the limits 
That is how I picked the boost for my Mustang GT blower package. Most guys who stayed below about 500 hp on a 300 hp 4.6 were not having trouble. Beyond that, it is a crap shoot for that particular motor. For normally aspirated, then total rpm becomes more important (pistons/rod speed)along with oil control so you don't starve the bearings.

I would be glad to share and have posted up some of the details on various Gen III Hemi forums but here's a link to follow. You can see from the onset we were determined to find out the answer to those questions ourselves:
http://modernmoparforum.com/topic/12184-...e-photos-added/
If you read through all the posts you will see that with a good tune and good fuel even at 25psi and a 150hp hit of spray at the launch the factory pistons did not fail or show signs of detonation.
As far as superchargers vs. turbo's on stock 5.7 or 6.1 pistons I have been blessed with the opportunity to tune close to 100 of these without any issues. Many of these cars, Jeeps or Rams are making 9-14psi and have been driven and raced for years by my customers.
I have no blow through Gen III Hemi experience. All my blowthrough tuning has been in the BBC world.

I just read that post. Any updates on that thread Mike?
Thanks for sharing, very interesting to say the least. I feel like going to work on the 5.7 sitting on the shelf at work that came out of a Ram. Can I hit you up for some tuning tips when the time comes?
thanks
Onig

About 600+ but you're limited on camshaft sizing with the stock pistons, so it's nearly impossible to make that power N/A anyway.

Pretty much all of them are reusable to point. Unless the engine has a ton of miles or got really hot.

Yes, that would work. No, it does not have vvt. Sounds like a good starting point if the price is right. Keep in mind the timing cover and accessory drive are different than on a car. You can't use the 6.1 intake without modifying the timing cover.

on this(timing cover and accessories)

Yep timing covers interchange. But a truck cover might be what you want if you're thinking turbo's since it mounts the alt up top.
Ok... but it might be too tall to fit under the hood
but at least I have options

Since you guys were talking intakes and the shorter intake tends to hurt the low end power.. was this on the carb version or injected also... might be hard to fit a tall intake on with a air cleaner and a throttle body.. or I might end up making a intake.... thoughts EDIT and later the hat and turbo would go on and loose the air cleaner
