traction is already bad enough on the street. im guessing a higher str makes it looser?

Nice choice of cam. Cant wait to see what she does......

I wish I could decide what cam to go with. Sounds like yours is almost exactly like AP's. His is .585 lift and yours is .587, maybe I will got .586...LOL

Naw, higher STR makes it a little tighter or nothing. The tightness/looseness of the converter if I have been reading right is the design of the impellor, etc combo of parts. The STR just helps get the thing moving at the initial point. Its a bigger hit on the line/take off. Esp. if you are on slicks, you'll get a better 60'.
