I do have an almost new one with a NOS FE intake manifold. This is my second Latham.
The first I bought in 1974 for $250 was for a Y-block and was the two carb version. Traded it for the 4 carb version and still have that. Still have the Y-block mounts.
I maintain a Latham Supercharger Registry and have documented about 100 still in existence, they are all serial# starting at 1000 and ending at around 1650 production ended in 1965.
Richard Paul bought the rights to produce around 1985 and moved production to SoCal. The new design is different and more for Tuner cars. I don't keep track of those. I've got lots of pictures of Latham installations. There were even Plenums with 4 downdraft carbs. I plan to build one of those. Here are my two larger pieces. The intake is not yet drilled for mounting the blower.
I'll post another comment with more pictures later.
As to Heo's comment about CFM, they do flow about 750 CFM at 5000RPM engine speed 30,000 RPM blower speed (yes 6 to one overdrive) supposedly @ 7 PSI boost.
