There's been a long floating rumor of the possible existence of 1964 Chevelles with solid lifter 327/365 engines and I think the block suffix code was even listed in Colvin's book several years back. I've kept an eye out for many, many years and have never even heard of a possible suspect car. In fact, '64 Chevelle 327/300 cars are extremely rare, let alone a 365HP version! I don't have a 1964 Assembly Manual to thumb through but there would be several things specific to a 365 car. Good luck with this one Dan!
