Anybody have any stories about aftermarket cams. Have seen something about oversize valves for same engine. Manufactures of parts would be nice. Would like to change cam and going to have valves replaced so might have well have larger ones installed if available. Exhaust and throttle body too.

 

Most folks on here used to recommend weasy but he's no longer active here adn I think stopped doing regrinds. I know DOA is selling some. Think they sell crower cams, which get mixed reviews but don't quote me. Colt cams get pretty good reviews on here too: http://www.coltcams.com/

To really get a benefit from cams you need to have your heads overbored and larger valves installed -- talk to engnbldr for heads and valves.

Once you run through the list and $, the 3.4 swap pays for itself...

 

These are good threads on cams:
