Crower has a great cam with the same duration but more lift..Num 32242 with 488/494 lift and a 112 lsa (install it +4 ) works good in a 440 or the 32243 with a bit more duration, both great cams for street cars. Im using the 32243 in my 71 Charger R/T and it runs 12s with stock converter and 355 gears. The Comp cam above is also a great cam.
