I have a 90 rs, 305, and am thinking about getting a new cam for it. I still want to keep the tbi on it, but want to go bigger. (of course). Does anyone know of some good options and maybe even some part numbers of the cams? Thanks, coco

 

Don't get too much cam. The 305 is not a good breathing engine and a big cam won't be able to help the top end because the heads and intake won't give it all the air it needs; however, the long duration & overlapwill kill your bottom end. Call one of the cam companies and they will recommend a cam that will work the best.
