I'd be interested in your dyno numbers when you get them. My combo is nearly identical to yours, also throttle body EFI, same heads but less duration and likely less lift as I used the OF 2 cam.

BTW, the Northwind was definitely holding back my combo, it had unusual cylinder filling for # 6 and # 8. My hood clearance would not permit a spacer, but if you can use a spacer some of that might clear up. Sometimes the throttle body EFI's don't like certain manifolds due to the way the fuel is dispersed- and this is a good example. The displacement is a typo- it's 467 CID.
