hi, CHH, yes thats the engine number i had on the log book and what the seller told me it was, i had a quick glance and thought yes thats about right but when we couldnt find a matching suffix number i decieded to get the brillow pad out and sand down the last 3 digits to make sure

sure enough it read CHH....

so for the time the engine has been in its had the wrong engine number on the log book so now im going to have to write to dvla to get it all changed properly....

sorry for the confusion....but thats what the logbook said it was so not having the experience with chevy and suffix number i thought it would of been right
