8BA road draft tube OD

[1948F-1Pickup]

Or the ID of the hole in the manifold for the road draft tube ?

Looks like 1 5/8" or so?

Thanks.

Not sure the exact dimension, but if you're possibly looking for a way to block it off for a PCV Valve mod, a Dorman #555-023 freeze plug is a perfect fit. Link to the thread if you're interested. DD

I believe he is asking about the size of the exterior tube on an 8BA type manifold.

Are they the same?

It is 1 1/4" where it enters intake.

Thanks for that. Greatly appreciated.

Do you need the tube?

Naw. When the engine gets back from H&H I'm going to install a ME Wagner PCV valve on it........ I refuse to buy an aluminum plug for $40 (Jamco) when I can machine a remnant piece of 6061 in 5 minutes.

or you could use a freeze plug, inverted, braze a fitting on it for the pcv...
