ROLLER CAM BUSHING

HI guys my bad for not posting lately,i have the bushings an would like to know are they hard to put in.an the other ? is do they let the motor turn more freely.thanks

Are you refering to the roller cam bearings? If so they take a cam tunnel thats machined for them.

The bearings are cheap. The machine work usually isn't.

Are they good for a blown engine.

I think they're good for any racing engine, but most guys will spend the money elsewhere, as hp gains are minimal for the money spent. I'd say that if durabilty is an issue, and you have the budget, then do it. I'd guess that you'll pay around $400 to get the tunnel punched out, Be advised that you MUST use a steel billet camshaft.
