I reckon the 72 degree cam will be perfect. This is what I was going to use in an L18 in a Sunny, that cam will now go into an L20B with a 32/36 DGV in a different Sunny & be road registered (fingers crossed). Was assured by both Stewart Wilkins & Arthur Jackson, both have other 30 years experience with L series, to use this cam. Good torque can also rely on port size,too big a port size can stall the air & cause delayed acceleration, usually when your trying to keep up with traffic, & somebody jumps into the gap just as the engine comes on cam. Good luck, sounds like the cam you had was a stocker, like my L18, which stopped dead at 5300 rpm.
