hemi 426 crate engine

Just as an example of cost : oem vs, aftermarket . A Hemi stock iron rocker is $125.00 each , last time I looked . An aftermarket aluminum roller rocker was $125.00 . No brainer there . A stock Hemi piston is $195.00 each . A, K.B. blower piston is $60.00 each . Stock Hemi parts are stupid money .
