With that LSA and those duration numbers I always thought that cam would be ideal for something with manifolds looking for a good kick, especially with decent induction. Intake lobe isn't much different than your 272/272 @ .050 (compared to the actual reported numbers on the 272/272) though from the looks of it, just a tad more lift.As I recall you were going low low 13s with that 272/272, weren't you?

I don't know if it will bleed off significantly more cylinder pressure, the advertised numbers are a bit more but Mopar is probably lying about those also. I know that 272 is reportedly a true 224 @ .050.

You could always retard the 272 a bit. Then again for 110 bucks its probably worth a try. Let us know how it works compared to that 272 if you do try it.
