Hughes Cam in Magnum - who has one?

Have a Hughes 544 lift cam and their valve springs in a 1988 5.9L Magnum with standard bore Hypertech pistons with stock rods and crank. Engine Quest magnum heads that are lightly ported and gasket match to the M1 Mopar intake. It has Headman headers and mandrel bent exhaust. Has a nice rumble and runs good.
