LT1 to LS1, LS2 or LS6
Can an LS1, LS2 or LS6 replace a 95 LT1. I am sure the PCM and harness needs to be swapped but what about things bolting up like the engine mounts and transmission or clearances.
Has anyone tried this?

you have no clue.... this is a nightmare of a project.
The fitment isn't the problem, really... what I haven't been able to get my arms around yet is how to keep the CCM and EBCM (ASR/ABS) functions alive... Without a working CCM, much of the IP is lost as is the electronic climate control.
If it was my $$ (which, at some point it will be!), I would do a 383 stroker and be done with it.

Reason I asked is I come across low mile LS engines from time to time that might need bearings, for free.
What do you think about the Edelbrock LS carb manifold or the after market fuel injection kits for the LS engines. Could you go that route and still keep the stock computer if you do a little programming?
I am not sure what power to expect with say, an LS6 with a carb VS fuel injection.
I am only entertaining the idea because the engine is free.

DON'T GO CARB!!!! That would really foul things up. And misses the point... do a carb, loose ABS/ASR for sure... and kill any value your car has. Also, carbs are sometimes tough to fit under C4 hoods. You have to be very careful as to which manifold you pick... then my favourite - CARBS ARE OLD SCHOOL.
The problem is ignition... the opti is one system... the LS1 is totally different.
If you commit to this, it will be a high dollar fix.
You may want to take the free motor, refresh it and sell it... then use the money to get the LT1 built.
I have been doing a lot of analysis on this project, and haven't come to any satisfaction. If you want to do an LSx in a C4, use a 1984-1989. No CCM to contend with, the climate and ABS are stand alone. Much less bull**** to contend with.

We're in the process of building a twin turbo LS6 (LS1 with LS6 topend parts) 6 speed setup to go into an 86 vette.
Looks like a daunting task, but may be easier on the older cars vs your newer vette.

That sounds like a better idea.
I passed up an LS2 the other day because I was not sure how hard this project would be. It sounds like a set of heads, a cam, and some long-tubes for the LT1 would be a walk in the park compared to an LS install. And probably have the same power in the end.Thanks guys for slapping me back to reality.

What 6spd are you using? The T56 is a problematic fit... the Richmond sucks... and the ZF doesn't fit up to the LSx block worth a damn... my... a real problem there!

we're using an f-body T56 with some bracket attachments that go on the tailshaft. We'll be doing some modding to the tunnel. I've been reading the progress of another members LS1 C4 conversion to gather up some tips on making the swap as easy as possible.
Are you sure that there wasn't an LS6 block? I am pretty sure there is since a lot of the F-body guys were finding that quite a few of the 01/02 F-body's had LS6 blocks in them. I don't recall the differences in them but I believe it was very minor.

The T56 is about the best solution for this... as long as you are willing to fit it.

I thought the basic difference between the LS1 and LS6 was all in the heads. The LS2 was the different block. Could be wrong.
I've contemplated down the road doing and bored/stroked LS2 in place of my L98 in my 90. Haven't hunted down the really bad parts of the project yet though. With less than 54,000 miles on her, I have some time to decide.

here is where the confusion lie:
in 2000, there were 2 block castings (12560626 & 12669378), but only one engine - the LS6 was new for 2001! In 2001, there was but one casting code, 12561168.

From what I gathered -
97-99 = LS1 block
00 = LS1 and LS6 block
01-04 = LS6 block
