Can someone on the forum provide me with a link that lists all of the suffix codes for Chevy engines? I have a casting book, and a Corvette book that has the suffix codes for Corvette motors. However, I do not have the suffix codes for non Corvette motors.

I have another thread running discussing my block. I am working another angle now to see if maybe there is an overlap of suffix codes. In other words, is the suffix code I am looking up in my Corvette book the same as the suffix code for '67 Impala meaning that I have an Impala motor instead of a Corvette motor. Just trying to run down all angles.

Please help. Thanks
