Actually I never had the 2031! When my old, untrustworthy mechanic built my motor, he told me that the cam he put in had .512" lift and 289° duration. However I had it measured and it turns out its an E-cam! I also listened to other Stangs with E-cams and my car has the same lope, but just sounds meaner.
When did you get that A-trim? I had my S-trim upgraded last summer from an A-trim after it spun a bearing. Best $500 I ever spent. I was seeing 8psi in 2nd gear but only 5psi in 4th gear on the dyno. After it was upgraded, I'm seeing 11psi!
