Seems like the 300 horse was dropped by then, the SS Camaro introduced the 350/300 so the 327 was down rated to 275. A friend bought a new 327/275, 4 spd. Nova and I’m pretty sure it had ‘462 heads and for sure it had a Quadrajet. In any event, nice find!
Either way, I am pleased to have found what appears to be an unmolested 327. I am going to do new oil and filter with new plugs, wires, and distributor and see if I can't start her up this weekend.
462's were the predominant head for the 67's, at least in the upper hp range, late 67 production could also have a "291" casting numbered head. The 67 Chevelle and Nova L79 option was rated at 325 hp.
