I just got a motor for my nova and was told it was a 327. I went on a ton of sites yesterday and am more confused than before. Here are the numbers; Block 3970020, Heads 3917293, Intake 3965577. If I'm reading right, the block is a 1970 307, the heads are 68-69 307/327, and the intake is a 1970 350/350hp. I wanted to build a motor similar in power to the L79 327/350hp. Do I have the right starting point or should these parts hit ebay?
