Default Re: Why the overbore from 396 to 402
The three letter suffix began on the new 402 CID blocks.
Their cylinders were overbored by .032.
Example:
Code JH is 396.
Code CJH is 402.(or 400 as Kurt mentioned)
I have seen late built 1969 Chevelles with the three letter suffix block.

You say no 1969 Camaros have been found with the three letter suffix,even thought the 1969 Camaro model was carried over late into the 1970 model run.
I would have thought those later built Camaros recieved a three letter suffix,as the Chevelles did.
Anyone know why they didn't?
