Ansen 1/2" thick aluminum 4 hole Spacer/Adapter for four barrel carburetors. Ansen PN CA639 8. (DISCONTINUED). Allows Holley carb to fit onto narrower carb mounting intake (Carter style). Has four holes of 1 11/16" diameter. Inner holes are counterbored for use with SHCS (socket head cap screws) for old manifold fitment. Carb mounting patterns are Holley 5 5/8" x 6 1/8" and old manifold of 4 1/4" x 6 1/8". See last two photos. Bought and used in the early 1970s with a Holley 3310 carb ('60s era 780 cfm). Will fit Holley 4150/4160 carburetors. No nicks or damage. Stored in a zip loc bag and a box and kept inside. Price $55.00.

Gaskets. None supplied. Uses Holley four hole on top and open gasket on bottom (for divided or open intake plenum manifolds).

1" thick aluminum open Spacer for Holley four barrel carburetors. Bought and used in the early 1970s with a Holley 3310 carb. Will fit all Holley 4150/4160 carburetors including 3 barrel. Carb mounting bolt pattern is 5 5/8" x 6 1/8". No nicks or damage. Stored in a box and kept inside. Price $65.00.

Gaskets. None supplied. Uses Holley type open gasket for top and bottom.

Notes: Must check hood clearance for any spacers to be installed. Four hole spacers are generally used for low to mid range torque and power increase. Open spacers are generally used for mid to upper rpm power. If unfamiliar with spacers, suggest looking at Wilson Manifolds and/or HVH web sites for info.

GM carb Heat Shield. GM PN 3969835. Was originally used on '60/'70s GM vehicles with Holley carburetors. Gaskets tear upon removal. No nicks or damage. Stored in a plastic bag and a box and kept inside. Price $35.00.

Gaskets. None supplied. Uses two Holley open type gaskets. Do not need to be stapled to aluminum heat shield as was originally.

Prices negotiable if can find same or similar aluminum parts cheaper.
