Bill,

there was a Holley "square bore" version of the aluminum intake as well, the part number cast into the runner for cylinder #1 should read D1ZX-9424-DA. That number is from memory, so forgive if I'm off a digit or two, but I'm fairly certain about the -DA suffix. I've installed several of them over the years. The casting number of the intake in the picture is D1ZX-9424-CA.

A previous owner must have installed the aluminum intake, as the oem intake for your motor was cast of iron.

Your aluminum intake is a good intake by the way, worth $300 or more. There's one business notorious for being high priced that lists them for $500 (Perogie Enterprises).

Okay, back to the quiz, doesn't anyone find it unusual that a 4 barrel intake manifold has the small 2V size ports?
