I really like this cam. I did go with Engle 993 springs @ 1.800 installed height to help with valve float. I was looking to make more HP (It made 340) than it did, but the Tq (375) in the low RPM range is all in @ 2200 and stays level up to 6000. I'm also running a 2800 stall in a 727 with a 8.75 rear end and 3.23 gears.
