Smaller cam is what you need based on what you state. That 260 at .050 cam on a tight LSA isn't going to be street friendly at all.

The 528 is a great cam. I run one in a 340. Something in the 230-240 at .050 range with a 108-110 lsa would be a lot easier to deal with on the street. Still have a choppy idle with better manners with a solid idle tune up on it.

Still spend a couple bucks on a converter. IMO, most important piece of the puzzle on an auto car. Converter tech has come a long way from the days of a high stall being akin to stepping on a marshmellow when rolling into throttle.
