7M8 CJ block
« on: October 27, 2018, 04:30:50 PM »
Would a 7M8 casting date C scratch block be a 135 series CJ block or just early CJ block or?

Might find some of this information offered a few years ago

I don't have any casting date data for the 135 cars though Kerry/sportyworty follows these details closely and has for years.

thanks jeff,  i did look but had not reread that article, which led me to cylinder block info, which states the C-scratch castings started in June of 67.
  so this one is not as early as i thought then.
