LS1,LS3,LS7 what are they equivalent too?
 

Is there a chart or something that can break down what the LS'S and what they Are equivalent to? I believe a LS3 is a 6.4L? but what would it be equivalent to in old c.i days?

I'd like to see a chart that says:
LS1 = 5.7L = 350 C.I (example)

Is there a chart somewhere?

I know this seems like an easy answer to you LS Guru's but hey I am alittle old school :)

Thanks

Hey Nova - I'm no expert here but:

LS3 = 6.2l = 376 cu in (if I recall correctly)
LS7 = 7.0l = 427 cu in

It's about 61 cu in per liter...

4.8 = 293
5.3 = 325
5.7 (LS1,6) = 346
6.0 (LS2) = 364
6.2 (LS3,9,A) = 376
7.0 (LS7) = actually should round up to 428, but 427 sounds a lot cooler

flash911 was on the money.

Note that all of the engines from 5.3 to 6.2 share the same 3.62 stroke.

also the 5.3 and 4.8 are the same block.

Here's an article that has a breakdown
