What's the differences between LT1s Question is about an LT1 out of a Caprice compared to an f body LT1. I know that heads on our cars are Aluminum compared to iron on Caprices/Impallas, but what's the differences (If any) in :
1- Short block
2- Harness
3- Computer.
4- Will a 96 LT1 timing set/cover and camshaft work on a 94 Caprice short block?
A local guy is selling his 94 LT1 from a caprice along with harness and computer and thought to pick it up to use the short block for a build.
Thanks guys.

The 94 b-body actually got the vented opti and the timing cover is the same as a 95 f-body.
The b-body had a longer target service life so the upgraded opti was introduced on it first. Figure a lot of these were destined for fleet service. Rumor has it 300K target service life where the Vette and f-body were only a 200K target service life.
The rank, pistons, rods are all the same per year. Biggest difference being in 94 LT1s be they b-body or f-body/Vette probably got pink rods not powdered metal. Not much of a functional difference. I just emntion it bevcause I can see you pulling the pan and assuming it is a b-body difference when it is NOT. Most people want to make WAY too big a deal about the differences.
On the service life thing that is a reason for iron heads, same wexpansion rate as the block means head gasket issues are about unheard of and the vented opti right from 94. So not much changed just subtle tweeks.

Thanks a lot guys, so the crank position sensor can be swaped as well and make it work on the 94 block ? Everything will be swapped from the 96 including the oil pan, timing set/cover, opti and cam as well, I just wanted to make sure than using a 94 block is no problem to have all these things swapped on it.

What do you mean by that? The Cranl Position sensor is on the timing cover am I right? So I can simply swap the cover along with the sensor and I should be fine right?
I appreciate all the help brother.

No need to swap the cam. The person who mentioned that did not realize the 94 b-body had the late opti design.
The cam is a little different and most would say a step backwards, BUT if you look at things closely a bolton b-body makes similar power to a bolton f-body.
