Default 67 corvette 427 "321" block usage

can anyone tell me when (if) the 321 block was used in any late production 67 corvettes, and if they were, a time frame for the use, some books show late usage, but usage unknown? Thanks for the help

Years ago I had a 321 block that still had the vin. It was a 435HP and was 5 from the end of production. Hope that helps!

321 was used late in 67.

It was the block the replaced the 351.

It carried over to the beginning of 68 model run.

You are both correct. I always thought it was odd that Terry M chose to find a '351 for that car. Especially since they broke a block during the restoration.

When you consider the '321 is both easier to find and less expensive when you find it, and certainly could not be considered "wrong" for the very last car, unless the use of '321 falls into the same category as '67 small block cars with factory big block hoods (i.e. highly controversial). Unfortunately, I do not know the answer to this riddle.

Per the '67 JG, the 321 block is possible on approximately the last 100 big-block cars.
