68 cuda

Yes, the 318 was the ELE police interceptor package with huge 75cc chambers, and the pistons were a shallow dish to get the cr up to 8.6:1 or so I'm told, so the 340 J casting had 68cc chambers, so I'm told, and that would give me about 9.2:1, I can tell you it accelerates, but how well will remain to be seen....I am tearing down a 360 for a stroker as of this posting, so here we go!
