Im looking for clamps for this manifold. I believe the correct clamps are the ones on the left. Can anyone confirm the clamp on the left is the correct one and if so, is it ford part # P/N B5A-9446-A that is 1.83" long?

 

Do you mean the one on the Right? The one on the right is the correct hold down for Y-Block manifolds. The left one looks home made.

 

I have been advised by another member on the forum he has seen the ones on the left before, but they are fairly scarce. I also found out the most common caps are like the one on the left. A "hollow" shell design that comes in two lengths. The one shown is the longer version for a two barrell maniflold I removed. There is a shorter version of it that is used for four barrell intakes. The shorter version is the about the same length as the one on the left. The ones on the left were removed from a four barrell intake I purchased on a 64 Ford F-100 with a 292. Since I have located NOS short cap version for a 292 project down the road.

 

I was just going thru my parts and found another compete set of the clamps shown on the left. Im thinking they are for sure a stock design.

 

The one on the left does look weird. Maybe it's just because it has been cleaned up. However, I have seen both styles on Y-Blocks.

 

Its cause I sanded all the pitting and rust off.
