There are always better parts for more money no doubt. My personal opinion is that the Eagle parts are a decent quality part, with this I am not saying that callies is junk because they are a superior part.

I think they are a good company that stands behind the parts they put in their motors and as you can see it is an Eagle Crankshaft in this motor..
The "SIR" Rods I can say I had success there too..379ci up to 225hp of Nitrous on a 500HP motor and up tp 7000RPM without any issue's.
As far as which part to use, my opinion is it depends on how much power you are going to make and if you are running N/A or not.
Like cnc-motorsports said I am not here to offend anyone just share an opinion.
