I noticed that. My dad runs a caddy/ Buick/ gmc dealer. The cts-v has spread ports and its a 388cid small block I think? It's all confusing as hell. All I know is there's no replacement for displacement if you're looking for power. Ls series engines are sweet. I've had my 383 for 12 years though and can't bring myself to replace it. If it breaks I will, and I try all the time to break it. When it does happen I'm going big big big block! Like 632 cubes. My uncle has a mountain motor from his 55 belair that got wrecked. 1300 hp. Ahhhh I'm drooling
