The Stovebolt Site Forums The Shop Area Engine Shop Production Code

OK I just got a 235 from a fellow Chevy Truck enthusiast and the production # has me a little confused, it is FI022A. The "I" is throwing me the curve. The only thing I could think of was the "I" could be a 1 then it would all make sense. Any advice?

I thought I read somewhere that all "I's" are to be read as ones.
Of course I can't find that quote today.

Look at the bottom of this page from the Keith Hardy site.

In 57' the engine code changes to:

Engine plant, month, day, type.

So using the info from the above site for 1957, your engine code would be

F = Flint plant

10 = October

22 = 22nd of month

A = regular 235

I'm not sure in how many other years the "A" suffix was used to designate 235's.

Hope this helps.

Thanks Randy I agree with the I for a 1, it seems I've seen it somewhere too but couldn't find it again.
