Do all A bodies have overheating problems?

When I bought my '72 Scamp, I installed all of the factory A/C parts. Radiator, shroud, fan, spacer and hood mounted seal to radiator core support. Also a 50/50 coolant mix with a 180 degree stat. No cooling issues. However, it is a stock 225 slant, but, I had all the parts on hand from an a/c parts car, so I put them in.
