EFI, probably Edelbrock Pro-Flo 4.

Interestingly, the PF4 manifold is 0.25" lower than my current manifold, plus the included throttle body is ~0.75" lower. The combined difference of 1" gives me more room to play with when looking at air cleaners - though the fat distributor in the Edelbrock PF4 kit could be problematic.
