Chev 216 loose piston pin - which one ?

No Mike, the one and two hole pumps are quite different. I think that the only components they have in common are the moving parts. The bolt patterns are not the same and the angle of the inlet stub is also different. Put the two pumps side by side and it is immediately obvious.
The one hole pump is the same as on the GMC 270 CCKW engine but for the pulley.

I too found the one and two hole pump housings to be different. I tried to use the adapter plate intended for two hole pumps to put a 1 hole pump on a later (261) engine and ended up having to make my own adapter plate. The general outline is similar but not identical and only some of the bolt holes are in the same locations.

Ok thanks for that info

I found out that my Rochester Carby has been fitted to the inlet manifold of the 216 with the vacuum port to the power valve in the carby blocked off I need to modify the base mount to fix this problem

Hi Mike

Depending on the application and year they moved the vacuum tap around on the manifold. Is the manifold off the engine? If so I would just drill and tap the manifold near the carb. Do not try this directly under the carb as the heat riser brings the exhaust gases up in that big area.

Another alternative is make an adapter plate for under the carb and tap the vacuum through the side of the adapter. This is how they tapped the vacuum for the brake booster on some of the engines.

Take a look at http://www.canadianmilitarypattern.c...ifications.htm some vacuum tap locations.

Cheers Phil

Ok Phil. Good information there on your web site . The carb insulator that sits on the manifold needs to have the cut outs for the vacuum port . My Rochester has the port drilled under the carb base .

I bought one of these

Looking at their web site , classicparts have 216 parts cheaper than other sellers, eg

Hi Mike

Don't remember seeing that source, will have to do some looking around on that site to see what they have.

With the new gas in the US the carbs really like the insulation spacer.

The spacer I'm talking about is little over 1/2 inch thick and fits below the insulation block.

Cheers Phil

Your 49 Lincoln project reminded me about the 1946 or 7 Lincoln convertible I helped to move , years ago. It was a V 12 side valve engine in that car . A similar car was in the Betty Davis movie about the 2 sisters .

The 46 was owned by a Kiwi , he shipped it from Melbourne to NZ , we loaded it onto a trailer and drove to the docks at Port Melbourne around 1 am in the early morning .

The car was stored down in a SE suburb and I followed in my ute as he drove it unregistered to Moorabbin , to await the trip to the docks on a trailer. As we drove to Moorabbin, The looks from the motorists at the traffic lights was a look of amazement , an old dusty crimson convertable with a white top and a huge long bonnet

Mike,
I must admit you have a knack for sourcing stuff. Looking at the insulator, it may not give you what you want.
Perhaps what you may need is one of those gaskets with the four notches. The four notches are there so as you can put the gasket on any which way and one of them will give connection from the vacuum passage to the manifold interior. Depends on the carburettor I guess.
