My roommate had a 69 Vette with the 390 hp 427 in it and that was pretty darn quick on the street, even with 3.08 gears. I can only imagine what the LS6 would feel like. Rear end was the weak link.

P.S. Me thinks the L-88 might have been the first "crate" motor. Didn't the LS7 have aluminum heads too?

i never had the money to buy one but the L88 was a 427 open chamber alum heads .the LS6 was a close chamber head engine with iron heads ? i think gm may of did them in open as well . they did the 396 /375 hp engine that was the same as a L88 but the bore .the Ls7 was open chamber alum head engine .alot of guys just used the two bolt block a cast iron crank 3/8 rods and used the TRW open chamber pistons with the open chamber heads.a poor boy crate engine

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.
