I have triple 40 DCOEs on my L24 with the E31 head and flat top pistons with valve reliefs. Compression is 180 PSI. This cam is close to yours. 214* duration @.05" lift and .420" total lift In and Ex. LSA 110* (Comp 260S). The 40's have plenty of flow and provide good torque with this street friendly performance cam. I previously had a 292 S Comp Cam with 246* duration @.05" and .480" lift. It proved to be too much cam for street and there was a real lack of low-end torque and throttle response. No power until above 4,000 rpm to redline. I hated it and jetting/tuning was impossible and it always ran rich with black plugs. Now it runs sweet, and I have tan plugs, great torque and the Z is much more fun to drive.
Webers love 3.5 to 4 psi fuel pressure which a Carter electric pump will provide without a regulator. I'd not use the stock pump. Hope this reply isn't too late.
