Do you think SM has their own foundry in China....that foundry probably makes many different brands of steel rods....Eagle...Scat...K1...and so on...
I have run both Hughes fast rate cams and "old" mopar cams....the MP590 is just as fast as Hughes 6064....MP cam 10.66...Hughes 10.65 in Bakersfield....Mp cam 10.78 in Vegas ..Hughes 10.79 in Vegas...same car...same engine...
Post your camshaft comparison ?
Current 71 Dart has "old" MP590 cam in the 360....10.38 @ 126.06 ....with Speedmaster heads...
