From what I've read and done searches on I cannot find a definitive answer to the question. Scat, Eagle, Callies, Lunati, Wiesco, etc... Now I know this is an extremely complicated question since a lot of guys mix and match different cranks, rods, and pistons from different makers, but what is the best quality of all of those parts all around? I am wondering what is the best rotating assembly in terms of reliability, quality, strength, and ability to withstand high horsepower applications for LSX engines?

 

Of those mentioned, I would think Lunati, but at a price.

 

Nothing wrong with eagle crank and rods, for pistons, Wiseco is on my **** list and so is JE, I could write a book on why I dont like them so dont pick them.

 

^ So what would your piston choice be and why?

 

diamond pistons, and callies crank and rods, either compstar or magnum

 

I know the callies compstar is their "budget" crank, but how much power can that crankshaft hold with a good set of their rods? How much for the magnum too?

 

depends on how much power, after about 1300-1500 hp you should go to a an aluminum billet rod which are huge bucks and need to be replaced every so often.

crank , there are a few places that make custom billet cranks and they are stronger than an off the shelf crank but cost huge bucks as well as take forever to be made. however with the lower priced forged cranks dont usually have problems when pushed.

pistons is alot of preference.

on a side note , i wanted strong stuff for my build 1200 hp area.

i went with a callies dragonslayer crank , lunati pro billet connecting rods and some custom coated diamond pistons.
