Re: 1964 C10 Engine Suffix - INFO NEEDED

Per the chart in the LMC catalog, a 64 V8 would be a 283 and the only engine id codes used on the 283 in 1964 were M, MA, MX, MY.

Looks like you don't have an original V8

The F is for Flint MI.

IM was used on 1969 350 Chevy/powerglide taxi. Not sure where IIM comes from.
