If it's a '94-'96, look for the LT1 code on the SPID label in the trunk. It can be in a 9C1 police package or in a civilian Caprice, as well as all Caprice wagons of those years, and all Buick Roadmasters, both sedan and wagon. From the outside, look for a "P" as the eighth digit of the VIN, and factory dual exhaust.
Not necessarily, remember, all caprices where also available with the L99 (4.3L V8)
Same desing as the LT1, but smaller bore. Like Vin Guy and Booth9c1ss said, look for a "P" as the 8th digit on the VIN. Only way to be sure. Even some 9C1 cars came with the 4.3 V8, usually for city duty.

The 1994-96 Caprice had the LT1 offered in 2 varieties:
9C1 police package with the 5.7 V8--about 285 hp??
L99 cicilian version had a smaller (4.3?) V8--about 200 hp
Hope this helps.
This isn't entirely true. The smaller 4.3 V8 in the 94-96 cars, while still a Gen 2 small block, is not an LT1, the name for it, as given to it by GM is L99. The motors are basically the same design, just the L99 has a smaller bore and stroke netting it 265 cubic inches over the LT1's 350. It is a HUGE difference when you drive 2 otherwise identical cars with an L99 and an LT1.
To make sure you get an LT1, do as these guys said. It has to be a 94-96 car, the 8th digit in the VIN has to read P, and as long as it still has the original sticker on the underside of the trunk lid, it will read LT1. Also, on the core support, on the emissions sticker, it will say the displacement of the motor, LT1 cars say 5.7.
The other way to tell. When you get into a 94-96 car and put it into gear, if you put the pedal to the floor and the car scares the crap out of you with how fast it is, its an LT1. If it only feels OK, then its an L99 (this is all assuming you haven't driven a huge fast car before, if you have driven a fast car before, it wont really scare you at all as there are a lot of cars faster than out LT1 B-Bodies). If you haven't driven many fast cars though, the power that the LT1 has will probably catch you by surprise, soon enough you'll be used to having it always there and you'll want more though

LOL! Excellent! Now I just need to sell my '90 Honda Accord. I'm leaning now toward a 94-96 Roadmaster as my thinking is that they are more likely to have been purchased by "old people" and taken better care of. The VIN numbers follow the same pattern? I still look for a "P" in the 8th character?

Yes. And the "LT1" on the SPID code label in the trunk. And the dual exhausts. Just don't expect it to haul @$$ from a dead stop, because RMs have either 2.56 or 2.93 (?) rear gears, depending on whether or not it has the towing package. Taller gears than an SS or a 9C1 with the LT1, either way. First stop after buying an LT1 RM: 3.73 ring and pinion. Then you will look like this >
Alright. I've seen this type of thread as a sticky on other forums basically just there to make small talk about small upgrades, customizations, or whathaveyou. I'll start it off and we'll see where it goes.
This weekend I managed, with the help of a Hoosier INC brother (BuiltBySparky on here)...
I'm looking for an organized data base, a library, a cache, of ... 1994-1996 ... 9C1 information, and it seems, that any (1994-1996) 9C1 websites, that existed, 10-20 years ago, no longer exist. I'd prefer to read up, on any data base for (1994-1996) 9C1's, before I start asking alot of 9C1...
I`d like to put a posi in my car and have rear disc brakes. That being said will the impala ss rear end fit between my skirts? I figure that would be the cheapest and easiest way to get both. Also once that is all said and done, what size wheels will fit inside the skirts besides the stock...
I've noticed a somewhat serious erosion of my fuel economy lately in my 1996 Caprice with the LT 1- B4U and 136 K. I use to get about 15 MPG which I considered reasonable but over the last year it has dropped to 12 MPG. I'm a volunteer fireman sometimes I get on her to get to the firehouse...
