The one hole pump is the same as on the GMC 270 CCKW engine but for the pulley.

Ok thanks for that info

I found out that my Rochester Carby has been fitted to the inlet manifold of the 216 with the vacuum port to the power valve in the carby blocked off I need to modify the base mount to fix this problem
