TOP END REFINISHING

[Paul Workman]

All the HVAC, cruise, etc gets it's vacuum from the starboard-side plenum nipple between #4 and # 6.

On mine I left the port side vacuum connector (the one that serves the SPTs) and a short piece of the hose tucked under the plenum. But, the hose is plugged, giving it an "un-altered" appearance. Same goes for the TB bypass. The IH is plugged, but I left the hoses "as tho" everything were stock. (That way Scottfab wouldn't have a cow if ever he saw a photo of my motor () (Oh, I like Scott a lot. But, he definitely sees thing trough a different prism than I do...make that MOST do! LOL!)

Hats off to you. You may not have all the answers (most of us don't), but you haven't let that deter you from forging ahead anyway. Serendipity is one hell of a teacher!! In the end, you'll know more about the top end (at least) than more than half of the ZR-1 drivers do, I'd bet! Good on you!!
