INT-403 — 2×4 351 Windsor Intake
The PME 2×4 351 Windsor intake manifold is offered with the 4-degree power angle and cut flat. Carburetors are mounted backwards to make more room and simplify installation.
Port dimensions: PME designed the port at 0.4″ up from the bottom and 1.9″ tall. Normal OEM heads are 0.315″ up and 1.97″ tall; most aftermarket heads are 0.365–0.400″ up and 2.0–2.1″ tall. For OEM heads, port down; for aftermarket, port up.
Both the 4-degree and flat versions sit level when installed. The 4-degree angle creates about a 0.9″ height difference front to back. They measure approximately 3.9″ from the end rail to the carburetor flange at the front.
Carburetors for this manifold: Holley 0-1848-1 (when available). Available in shiny aluminum or zinc with Gold Dichromate finish.
