I’m not an Eagle fan either and have used K1 and Molnar by choice in my builds. With that being said I bought my R3 block in a group buy with an Eagle crank and Eagle rods. Everything was checked over by a machine shop and it sat for years. So I checked everything over and assembled it and ran it for five years. It was shifted around 7000 rpm and ran 5.98 in the 1/8 and 9.38@138 in the 1/4. I have Molnar stuff that will be getting balanced and going in it this time. My buddy bought my old Eagle assembly.
