The original Stealth is #8016, which Weiand no longer makes. If you shop around, you can still find them for sale new....the carburetor pad height on the 8016 is 4.18" front, 4.50" rear (high-rise, dual-plane).

The 8016 is comparable to the Edelbrock 7101, Holley 300-36 (not to be confused with the Holley 300-36S) and the Professional Products 52020 (polished), 52021 (satin) and 52022 (real-chrome).
Here's a dyno comparison between the 7101 and the 52020....

If using L31 heads, use Edelbrock 7116 or Professional Products Crosswind Vortec 52027 (polished) or 52028 (satin).

It's a matter of opening up the top end of the motor with a good high-rise intake manifold and 14x3 or 14x4 air cleaner and letting it breathe out through a good set of tuned headers with X or H pipe, properly sized pipes and mufflers. A high-rise intake is good for about 40 hp over a low-rise. Tuned headers are good for at least 50 hp over cast iron log manifolds.
