Porting the edelbrock 2665
#1
i picked up an edelbrock 2665 to go on my 4v along with the new cam. i cant help but notice how much smaller the ports are on the edelbrock vs the factory cast manifold. ive done my share or manifold and cylinder head porting and polishing as well as acid and extrude honing but that was all on import engines (the mighty mitsubishi 4G63 Wink ) . so im wondering if anyone has port matched this manifold to fit the head or not.

The 2665 was not real popular because of its small runners. Made for quick off the line feel which is why the small runners but power faded real fast as rpm's went to 4 grand and about fell flat on its face after that. Took mine back off and again used 4v cast iron till I found a Blue Thunder, but that's just my opion

Buy a Blue Thunder. Really woke my 72 Q code up! The runners on the 2665 are way to small for a 4v motor. Had that intake on my engine for awhile, was very disappointed.

This will give you a better idea of the mis-match. They are not concentric.
