I bought a '69 340 about a year ago that was said to have approx. 12k miles since a rebuild. The previous owner acquired it with a car he bought and really didn't know many details of the engine. He did say it is 11;1 CR. I installed it and ran it this past summer and just pulled it today for some upgrades this winter. This looks to be a stock bore and the pistons are approx. .010 above the deck. I'm trying to calculate CR for cam selection. Any help is much appreciated! Thank you all....
