Desperately need experienced opinions on Engine Identification
2658920 – 1967, 273 LA-series small-block, 1.88/1.50 valves
IMHO this is a misprint and has been around forever. Nowhere can I find a reference to a stock 1.88 valve in a 67 273.
If you can shine a flashlight into the spark plug hole and see 4 valve reliefs (you may be able to see the 2 facing each other) you got a 2bbl. The 4 bbl pistons had only 2 reliefs on the valve side. May be impossible but a Depstech USB borescope is like $20 on amazon. Here is my 2bbl 273 through the spark plug hole. notice center stamp and universal reliefs
