i got a set of mega cycle cams in a deal, the previous care taker let them sit out and some of the lobes got rusty. i called mega cycle and they said they can be corrected, they will give an estimate. i will not be building an oil cooled any time soon. if someone wants them for FREE, i want $20 to cover shipping them to you or to mega cycle for you. if not round file real soon. i have no idea on the extent of the damage or a guess at the cost to correct them. they are not useable in the current condition. first come first serve. use my e mail link i check it more often. they are 395x5 drop in no guide work required.
