Icons and 4.0 rods or Ross pistons and 6.150 Eagle rods

[floundering]

I've been lurking here a little bit and trying to soak up as much knowledge as I can but there is a lot of info to weed through. My number 1 priority with this engine is longevity as this will be my daily driver. I however don't mind spending extra money if it will yield more horsepower and be just as reliable.

I would like to do a 4.7 and it seems like the most common direction is the Icon pistons and 4.0 rods or the 6.150 Eagle rods and Ross or Diamond pistons. The cost seems to go up quite a bit with rods so I was just wondering if this equated to more horsepower or are you just getting a more durable product? Another thing I notice is it seems quite a bit cheaper to buy the parts separately rather than the package. Am I missing something or are the packages really just bring up the price?

I've been looking at Clegg's, 505, and Hesco. Any other sites worth looking at?

Hi, I'm doing a more low buck variant with the 4.6 for a DD and everything I can to keep the costs down (to a point). I noticed the costs for the assemblies looked pretty outrageous given the individual parts costs too. I'm sure there is a lot of variation as to why, but I'm willing to bet a lot of it is to take the guess work out of what is needed.

The benefit of the longer rod is that the piston comes out of the bore less at BDC and technically the longer rods should give more torque, as well as having a forged piston. Besides the pistons you listed the Keith Black IC944 piston will work with the 4.0L rod. The 4.0L rods are good for 400 HP and since you mentioned the eagles rods they will surpass that number.

The problem with the kits is that you usually don't know what you are getting as far as piston rings, bearings, lifter and other small parts. Also, they are for ease and the seller needs to make a profit for putting the kit together.
