I have never got any cam maker to give me the time of day when asking about Hydraullic roller lifters for a chevy 6 cylinder-- trying to get them to put other (olds) tie bars on sbc lifters.
if any one knows who will----or a contact - past a "gate keeper" please post. The owner of comp cams is just Too Damn Important--he's got to hang out at the golf corse--NOT THE PLANT!
