My motor guy says this, he has builts tons of motors with all kinds of different parts, he has yet to brake Eagle Stuff so he keeps using it. My motor 582 with eagle crank and rods with upgraded bolts made just under 1000 on the dyno and runs 4.6's in my dragster. A buddy of mine has a 598 with same stuff as mine but on gas he runs 4.8's in his dragster and sprays it 285hp the whole 1/8th and has several times and not broke yet.
Now the scat a buddy put this stuff in his 421 small block, rod made it 6 passes if I remember correct.
