360 vs 383

i'm not gonna take the D300 to the strip,
LOL .. i get it, although I might :D . I'm just saying, are both engines 100% up to snuff? Any updates on one vs the other? It's very hard to hold 50 year old vehicles to a standard of 50 years ago, so many changes between then and now. And were those changes equal? I guess that's why I said there is a lot of property there to cover, but I get your comparison.
