What do I think??? Well, it has pretty much been worked over in this discussion already. Big block Corvettes were pretty near as close to an orgazm as you could get on wheels. I had a '64 with the 365 Mouse, and it was quick and went like stink once it got above 2 grand, but when they came out with the big block in '65, I always felt out classed; I lusted for a big block. Starting with the first 396s in 1965, 427s in'66, 454s in '70; they all had so much grunt that they were hard to get hooked up, and when you did get one hooked, it was brutal - quick and fast. And swapping back and forth was/is not at all a difficult thing; you just need to get the parts for that particular app. - eg.: big or small block; nothing more to it but the sweat. In my mind only one other car had anywhere near as much raw, brute sex to it; the 427 Cobras. Makes me feel giddy just thinking about it - even today, forty years on.
