I want to know what you guys think about this. My dad told me back in the 70s his one buddy took a 454 LS6 out of some kids wrecked 70 Chevelle and dropped it in his '68 Corvette.
(Sadly he put a hole in the oil pan from going over a high speedbump. He tore the engine apart to look for damage but it's been sitting in his garage for over 25 years now in pieces.) From what the old man was saying, that corvette moved like a 67 SS Chevelle times about 3.
the LS6 was a very good engine put it back together with a bit better cam and you will find out why a bbc is hard to beat:D
yep--they were one of the first crate motors---oil pan to intake, add carb and dist---or was that the ls7???? one was 11:1 cr and other 12:1???? one had press fit rods/other the full floater plated ones///Damp, head hurts trying to remember
Floaters are the way to go, I order those for everything I build.
Just my prefrance though, I don't want to get anyone mad. Kurt
LS6 was not the crate engine if back in the 70s the ls7 was open chamber BIG DOG over the gm counter deal with 7/16 rods floating with killer rod bolts with a green stripe crankQuote:

I remember they had a sign at the end of their parts counter for those engines, $995. This was at the same time I was buying & selling complete 426 Hemi engines from wrecked cars for $750-950. Sure would love to have a couple of those now!!! :CRY:

well that was a hell of a deal wish . wish i had some of them hemi s we had
Yep Back in them days the hemi's were cheap to buy used but
expensive to rebuild. I used to help the guy acrossed the street
from my Dad house build them. Thats what I started out racing
when I was a kid growing up in Las Vegas.
But after a few blown motors and lots of walking I started building
Fords. I've had lots of good luck with small block fords. Kurt

As I was reading your post, and you being from Seffner, I was thinking maybe you lived across the street from Don Garlits, but then I saw Las Vegas---shucks

thank you MR. MCcarthy!!!!!
Well nightprowler, Chevy put the LS6 in the 70 Corvettes (pretty much the same as a 68) right from the factory. And indeed they did haul a$$. NHRA had them in A/Stock if I remember correctly which pretty much put's them at the top of the factory heap. 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?
that was a miss print on the box should of said mean rat in side :eek:Quote:

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. ;) :)
