I had the 270s in my 4.6 but have since sold it. I haven't run across anyone running the 262s. I've read thru a lot of threads and it seems that which ever one you have was the best choice. Can anyone tell me which one is the better cam for the L. BTW I'm using a stock block '99 with a '01 maf and a 6lb. pulley. I have two buddies willing to give me either set. Thanks
