Fellow Stovies,

I have a 1966 Chevy i'm using for parts. It has a running engine, a 250 according to the po. The engine casting code, which is behind the distributor, begins with 'FO'. I have looked at inliners.org along with a few other websites, but I have not been able to find anything on a 'FO' stamp. Could any of you direct me to some other sources of information on inlines?

Any help would be greatly appreciated.

I think FO are probably the 1st two characters? My 292 #'s start with FO but, it's the last two characters (UH) that tell me it's a 292. Got any more characters? If you've got TA, TE, TF, SV, SW, SX then it's a 250.

FO705TAC is the complete number; if I disregard the 'C' on the end, that comes to 'TA'. 'TA' is a 250 according to the link you gave me, Chuck. I guess that's how the numbers come out........no idea what the 'C' is for.....

Or it's really a TAC out of a 73/4 Blazer. May be rebuilt/replaced.
F = Flint
07 = month = July
05 = day
TAC = 1973, 1974 Blazer/Jimmy 250

Look for a casting date code to find the year. These are V8 locatins, but the code is the same.
