1955-1957 Ford Thunderbird 4 Barrel 4V Aluminum Intake Manifold, ECB-9425-B 272,292,312 - Satin

Very nice manifold

This manifold is a near-exact reproduction of the '57 Y block four barrel intake. I have measured every dimension and it's spot-on or so close it doesn't matter. Every hole lines up,ports fit the heads well,all threads are excellent and the casting is very well done. It's far lighter than the original iron intake and that's a big plus. The bores are 1.5", just 1/32 per side less than the throttle bores of a Holley 600. A light chamfer will make a nice fit. It's such a nice addition to the 312 it's on!

Looks great. Haven’t installed yet but anxiously looking forward to it.

Looks top quality! Machining looks great ! Can't wait to fit it.
