Here's another avenue - if you go to the L-48 section, sheet A2 (non-illustrated parts) and look in UPC 6, item 6L (intake & exhaust manifolds & heat control) and 6T (air injection reactor equipment) carry the symbol for "assembles same as production", which refers to the base V-8 engine. Then go to section M35 (Powerglide), sheet A22, and it shows the base V-8 engine with the thermostatically-controlled air cleaner and exhaust manifold heat stove (no air injection system). If you have a THM-350, in section M-38, sheet A2, it shows that those items assemble the same as with M35.
