Y-Block Intake Interchange

[joze93]

I am trying to install a 1957 4V intake on my 1955 272 engine. I have tried 2 different manifolds and each one "rocks" from side-to-side, because the front of the manifold rides on top of the valley pan before it flushes with the heads.
Is their a difference in 272 and 312 valley covers? I have been told this interchange should work. Help!

B6A6519A .. Push Rod Cover

Fits: 1954/57 Passenger Cars / 1955/57 T-Birds 239/272/292/312 (except 1957 312's with Dual Quads or Supercharger).

Fits: 1954/56 239/256/272 Trucks / 1957/59 272/292 F100/750.

The 1957 4V manifold should fit just fine as this was a very popular swap back then as the "toilet bowl" carbs used on 1954/56's were crap.

What I'm wondering is...what 1957 4V manifold do you have? What's the ID number on the manifold?

If it's off a 1957 Ford/Merc passenger car, or Bird, there should be no problemo.

If it's off a Lincoln Y block, or the 1952/63 279/302/332 versions used in F800 and larger trucks...it will not fit.

btw: What's the 272 engine installed in? 272's were only used in 1955 Passenger Cars/Birds. Trucks didn't use 272's until 1956.

Bill, The 272 is in a 55 Victoria. What are the chances that I accidently got 2 4V intakes that came off engines with milled heads and the intakes were milled also? Is there some way I can measure to determine this? Thanks for your reply.

Sorry, parts catalogs do not list manifold dimensions.

Is there an ID number on the manifold?

Bill, Thanks for your help. I found another valley cover off of a 57 292 that is "flatter" on top and clears the 4V intake. The 55 Victoria valley cover had too much "dome" to fit under the 4V intake.

Regards, Joe

Got any pictures of the 55? I have 56 town sedan.
