Black- 1996 Impala SS
LS1, LS2, LS6 and LS7
I'm an LT1 Impala SS guy. I know the LS6 is a 6 liter and the new LS7 is the 7 liter, but what's the deal with the LS1 and LS2? What's the displacement of all the engines and can you guys interchange parts? I have seen numerous LS swaps and am just not familiar with what all the different designations are about.
Thanks

Red Tint Jewelcoat- 2008 Trailblazer SS
LS6 - 346 (5.7)
LS1 - 346 (5.7)
LS2 - 364 (6.0)
LS7 - 427 (7.0)
They are mostly interchangable. But not 100%.
Bore changes from the LS1 to the LS2 to the LS7 making the blocks a touch different as well as the internals.
Sensors have moved on the LS2 over the LS1/LS6 as well.
The LS7 looks similiar, but has several changes over the other LSx motors.2008 Trailblazer SS

Black- 1996 Impala SS
O.K.
So the LS1 started in the F-bodies in 97 or 98? When did they start in the Vette?
I wonder why the LS6 is a 5.7 instead of a 6 liter? I thought the 6 meant 6 liter???
Which came first, the LS2 or the LS6? And did the f-body leave with the LS6 or the LS2??
When did the Vette's get the 6 liter?
The LS7 is definetely an awesome engine. Does anyone know what GM is selling this crate motor for? $$$$$$
Thanks alot guys! I'm just trying to get this all in order. I've been out of the loop for longer than I thought!

LS1 started in Fbodys in 98. Started in Corvettes in 97.
6 doesn't mean litres. Otherwise the LS1 would be 1 litre and the LS2 would be 2 litres.
The LS6 came before the LS2, found in C5 Z06 Corvettes.
Vettes got the 6 litre LS2 in 05 when the C6's came out.
I think an LS7 crate engine costs somewhere between 15-20k.

The LS1 started in 98 for the F-bodys.
F-bodys never had the LS2 or LS6.
I believe the LS6 came first.
I believe they are selling the LS7 for around 15k-20k.
HAHA cascade got to this before me! his sounds right

Also, all LS7s are handmade... There's only like, 15k made a year, or something.
And all the LS-series engines are based upon the LS1 architecture, with modifications stemming from that...

I can't wait to see what happens with the LS9 and LS8. And the 08 GTO is getting the LS3 with a rumor of a slightly smaller motor, the L76.
LS9 - superchagered, intercooled 6.3L smallblock, ~650+ hp
LS8 - supercharged 6.3L smallblock, ~500+hp
LS3 - N/A 6.2L smallblock, ~430-450hp
LS1 came in the vettes in 97 and f-bodies in 98
LS6 came first in the C5 Z06 vettes
LS2 in C6 vettes and 05-06 GTO
LS7 crate for $15K

Didnt some of the last models of the F-bodys have LS6 blocks?? I wanna say I 've seen people talking about this. Something about GM running out of LS1 blocks and having to use the LS6 setup.
