My 65 vette has a 1968 327 block with 66 heads and manifold. According to the previous owner, he built the engine to the 66 327/350 hp specs. Because it's a 68 block, the crankcase is vented at the valve covers. I recently replaced the pvc valve. When I went to the local autozone to purchase the replacement, the salesman had one for a 66 and another for 67. I chose 67 since the 66 vette is not vented via the valve covers. Could my selection of the wrong pvc valve cause problems or damages with the engine? Finally, how can I be sure of the correct pvc valve if correct selection is critical to the welfare of the engine? It's too bad the engine is not correct for the year but someday it will be! Sure will be a lot easier in purchasing the correct part.
