Do all LS blocks have the same engine mount location? Exhaust port location? Like is the LS1 the same as LS7? For mock up purposes I might use a junk engine is what is driving the ?
Thanks

Any one on the LS1 tech site has a answer?

Yes. All LS engines use the same mounts/locations. Exhaust port locations are the same, sizes and shapes differ depending on type, but the location is physically the same.

From a 327 to 454 all with the same size external dimension LS block. One of those big things in a little package deal depending on what foundation you choose to go with.

Yes you can use any blown up LS series block for mock-up purposes. My foam mock-up block works for EVERY LS series engine and should fit all the vortec series also (LQ4/9 and smaller 4.8 and 5.3).

What you're asking is how to re-purpose an aluminum LS that chunked a rod through the block or otherwise broken to the point of non-rebuildable.
