There's quite a difference between the Scat and Eagle castings. The Eagles will literally break in a stock rebuild application. LOOK at the cross section of those cranks leading up to the rod crankpin. Ridiculously thin. Absolute garbage. The Scat's castings are thicker and more money. At that point might as well put a steel one in it. Why throw mallory in a stupid casting anyway.
My mate just ordered a 4.150 Eagle kit to build his 493BB, I told him no, lets hope it holds up, its a 650>700hp brkt build.
On the SB stoker we got a guy here who runs a very mild 340/416 in a sorted Demon in our NSS class>
