Non-FE Discussion Forum / Worst 4V intake manifold Ford ever cast?
« on: September 23, 2023, 01:59:35 PM »
I have just picked up a couple of '83-'85 302HO 4V intake manifolds, and wanted to get some flow figures for them. I had a Stock Eliminator racer ask about porting one, and I offered to do so as I had time. He never followed through, so when a couple of the intakes came up on Craig's listing locally, I picked two of them up for $125.00. The ports are tiny, the manifold is definitely a low riser, and just looking at it makes you wonder how the Mustang ran so well for the era. I have flow figures for 292/312Y block 4V intakes, Lincoln Y blocks, 289 iron 4V, 302 4V, and all the FE's/429/460s/4.6modulars/5.0HO EFI/5.8 EFI from the last 35 years using a flow bench. This little intake manifold only flows 140cfm average, and the '83-'85/E7 heads flow 169 cfm as cast. Not a single runner flowed over 158cfm. Here are a couple of pictures of the intake manifold.
