I would run it all it needs is a little cam advance and it will kick ##$. you should upgrade the springs to 33's or some comp cams ones
http://chucker54.stores.yahoo.net/valvesprings2.htmlThe 509 is a great cam and in a four speed it will be fine. Most inexperienced posters don't know how to set them up. They are best with mild no brainer cams. Hey if it don't work installed as I say it's and easy enough out!!! (but it will work)So Install it with the intake centerline (max lift) at least 4 advanced in at 102 or maybe even 100 and it will have all the life and pop you want!
I personally love this cam for the street and light strip. But unlike most above I like all the power you can get and have learned over the years how to make bigger cams work to get low end and max power!!
