My

My first experience with SCAT I Beams: 250 +/- runs in a 12:1 416, low 10's @ 3100#...6800-7000 at the stripe every run. We lost a couple of rod bearings due to oil detonation, and those rods were "blued" from the heat and out of spec obviously. But the other 6 were within spec that a resize would have made them reusable.
I have heard of many failures with Eagle I beams, though never ran them myself.
Your dead on about the cost or remanning a set of 40 year old OE rods vs, the SCATs. Better material, cap screws and much lighter than the OE rods.
SCAT's are going in a warmed up 340 I'm doing for a guy right now and will be in my street/strip small block for sure.
