eagle
Well, since no one else is getting this going, I will try.
Both brands you are considering are offshore, China, forgings.
I prefer Eagle myself of the 2, but both will work for you.
Eagle's are finish machined overseas too. I am not sure about Scat.
Check to see if they both have at least ARP 8740 rod bolts.
H beam are stucturally better design than I beam for those brands.
Check you bearing clearance carefully as they may not have correct clearance with standard rod bearings.
