N47 ? / Carb mounting

[TBK1]

guys putting back together the 280 motor with n47 head for install in boys 240, using his downdraft carb setup and headers,

question is the n47 has 3 screw holes above the intake ports, the outside 2 are for the intake mounts but the center one that isnt used for this setup do I have to plug the holes? also used the gasket for the 240 vs 280 that doesnt hace thecutout for the injectors, asummme this wont cause any problems?

Hi Don,

Well having done this myself, the extra hole shouldn't cause a problem unless its drilled through into the head. I don't think they are though. Just leave it empty. Using the gasket for a carbed engine is fine also.

I put a the stock carb setup from a 72 on a 76 engine and it all worked for me. No surprises.

Have fun,

Chris A.

On my P79 head the extra holes are not drilled through. I left them empty and all is fine.
