Found a replacmnt LT1, 95 Caprice, thoughts?
Hey all,
I have been looking for a replacement LT1 for my 93, and have come across an LT1 out of Caprice police car w/headers.
I am having a hard time finding just what hp those engines were rated at, and/or the difference in my current LT1 vs the other.
Can anyone please help clear this for me?? The Engine (full access) and headers is selling for $600, so I already know the deal is good.
Thanks all!!

not really.
That's a 185 hp motor. The upgrade LT1. It is also 2 bolt mains with iron heads.
Are you looking to rebuild? If you are, then the bottom end is giving you a good starting point. Take that block, tear it down, get a 383 (or 396) rotating mass, get it all balanced and such. splayed 4 bolt conversion...
Get good heads, perhaps the LT4 top end kit or a set of AFRs or something, LT4 hot cam and go to town.
450hp is yours. drool.
Oh, and there is no promise those LTs will fit inside a Vette.

Crap..
Well, I was toying with either rebuilding the current engine (bad knock on drivers side, bent valve possibly.. Not to mention a huge miss.. But I figured I would find out on the other.
I am confused a bit though.. I know the LT1 out of the Caprice Impalla SS is rated at 260hp. So the LT1 out of a same year Caprice police car is a completely different LT1? Side by side they are identical to the look.

Bogus is right on.. The 2 bolt main blocks were used in the caprice and camaro.. We have 4 bolt mains in the C4's.
IF you want to do the build up bogus described the 2 bolt main is the place to start so you can splay the main caps for strength. To my knowledge the block will bolt right in but you will need to convert to all of the assesory drive hardware from your vette of course.
I assume the guy is referring to the type of Cam that is in the car. However, there are "Solid Rollers" "Hydraulic Roller" and so on. I would assume it is a stock hydro roller engine

Most times people don't put a solid roller in a mild engine.. it may be a thumper !!!
Worth more inquiry if that is what your looking for

There's two iron headed GenII motors in the Caprice, the LT1 and the L99. The LT1 has iron heads, it's the short block as the Vette's, except for the 2 bolt 4 bolt issues and a smaller cam, 260HP/340ft*lbs. Same rods, crank, pistons, lifters, oil pump etc. The heads are iron, weigh 50lbs more than the Vette LT1's aluminum heads, flow a little better. Same intake manifold, valves, rockers, different valve springs.
The L99 is a low HP 265 ci V-8, looks just like the LT1, I think the block has L99 or LT1 on it, down by the oil pan.

As for the interceptor package being so good I doubt there is much difference. Plenty of cop cars turn into taxi cabs after their useful life and I think you will agree that there is nothing "special" about those cars

The cop car Caprice (9C1) has an external oil cooler, external PC cooler green hoses and a thicker frame. The Impala just had the thicker frame.
