I think i got screwed. the cam he said he put in, dosen't seem to be what's in there. Is there any way to check without tearing the engine down? Maybe some way to put a dial indicator on the rocker and turn the engine over. I'm planning a upgrade and need to know what cam i got. any help would be greatly appreciated. And thats the last motor i'l have him do. Thanks. Zappo

It's possible to use a dial indicator with the tip set carefully on the edge of the retainer to measure cam lift and duration. NHRA uses this method to check cams on Stock Eliminator engines. In order to get accurate measurements you'll need to use a solid lifter instead of a hydraulic. Also, when you set the indicator point on the retainer be careful to align it to exactly parallel with the valve stem or the dial tip will move across the retainer as it depresses and you'll get a faulty reading.

Thanks Chuck, but there hydrolic lifters, if i have to tear it down to switch out lifters then i might as well pull the cam. I don't want to tear it down with summer around the corner. guess i'l wait till i'm ready to do some improvements and include a new cam. thanks for the help. Zappo
