Mike, and all,

Having known about this issue after I bought the F4B (slightly used) / 
Holley 1848-1 (new), I had the Edelbrock US version intake, rather than 
the Rootes LAT-1 version.  Needing to bring this up to the Rootes 
version, I had the temp sensor thread hole welded shut with aluminum 
heliarc, and re-drilled it to match the Smiths original sender thread.

A simpler way would have been to buy a "thread-sert" system, and drill 
the hole out and tapped, and inserted the adapter. (dissimilar metal 
corrosion aside)

I also made the lack of a PCV dedicated throttle plate on the 1950's era 
new 1848-1, I purchased a 600 CFM Holley base plate, and it bolted right 
on (less a substantial fee to the parts dealer).

THE Rootes LAT-1 version had a front, left side front intake runner 
blanked boss drilled and tapped for a hose input, that ran to the PCV.

To learn how to skin a cat, properly, it takes some experimentation, and 
a number of cats.
