95 LT1 vette engine
95 LT1 vette engine What are the differences? I know that heads/cam are different than the LT1 in my 95 Z28. What else is different? someone I know has a 95 LT1 engine out of a Corvette I'm gonna check out maybe buy that and start building 
. But if its not able to run on my pcm and wiring harness then there's no point. Just go ahead and give me any info you got.

The cam's in the 93-95 Y-body and F-bodys are the same. Im assuming the heads are the same also. Also I believe the vettes cam with a 4 bolt main block
Vettes have the same block casting, just machined for 4-bolt mains.
Despite you wanting to blindly put the Vette motor on a pedestal is is indeed the SAME as the engine from your 95 f-body. The power rating difference was maybe slightly in the intake tract and exhaust but mostly just on paper.

Unless you want to build another engine while still driving yours and/or you just want a 4 bolt mains, you might as well rebuild yours. The 'vette engine is basically what you have. The cam is only slightly different and the heads are the same.
I probably will use a different cam in the engine anyways so I don't really care about having the vette cam. Just want 4 bolt mains. Any way I can tell that it is out of a vette tho in case this guy is bs-ing me? Like casting #'s? Trending Topics

What would it matter? Youre building it right? So, In theory, an LT1 is an LT1. Nothing different for the blocks other than how its machined for the mains. Bottom to top build, you'll build it to run off of your PCM. Hell, it will, I'm just saying, I'm sure its plug and play.
Exactly..the only thing different really in the LT1 Harnesses was the Crank Position Sensor. I know that the 1993's and back were batch-fire so maybe that one is wired different on the PCM Connectors..
By the time 4-bolt mains are of any value you need aftermarket caps, making a stock 4-bolt main block about pointless to start with.
Let me be a little clearer on the block thing. THERE IS ONLY ONE BLOCK CASTING for the LT1 and LT4, 4-bolt blocks are the same block as the two bolt.

Oh damn so the vette engine isn't anything special over the Camaro. I'm just looking for basically any LT1 right now, as long as it is in my price range. And this guy doesn't want much for the motor so I'll see what happens 
I would not turn down a 4-bolt block but I would not pay extra for it either. Factory 4-bolt means a serious build would just use aftermarket straight 4-bolt caps. I wont get into the straight or splayed argument but I will say EITHER will work wonderfully. IF there is a difference it is WAY WAY beyond what someone looking for advise here will achieve.
I ended up buying a 50k mile "midblock," I'll call it, 95 LT1. Basically a stock shortblock with everything but heads and intake and all the top. It looks real good and picked it up for a low price of $200. I plan on doing a nice heads/cam setup over the winter, stock cubes. Put in some new piston rings as well just to be safe. Not sure what to go with for heads/cam though, I'll post a thread about it soon. However, after seeing this thread I think I have an idea:

Or you could go this route.
