What year is my LT1 ?? Hi Guys; I picked up an LT1 w/ a 6-Speed transmission for a song a month or so back and have NO idea what year Camaro it came from? I decoded the numbers on the T-56 tag and determined that it was MFG'd in August '95....my guess would be that the motor was also a '95.....however, when I pulled the accessories off the front, the timing cover has the hole in the bottom for the crank positioning sensor which according to a website I ran across, indicates it's a '96+
Maybe knowing what year the LT1 is won't cause any harm when ordering the aftermarket wiring harness and other items, but I'd still like to know...
Thanks in advance for any and all input!

I'm not sure whether it had two cats or not since the motor was pulled out of the car. There were headers on it with a pipe (and perhaps a hollowed out cat???) that ran from the drivers side over to the passenger side header collector.... near as I can tell, there was only one... then again, I'm unfamiliar with the LT1 and Camaro's in general so I'm not sure what the exhaust system looks like.
The new model year starts in August or September of every year. If the trans was made in August of 95, it went into a 96 or later car. Also, only 96 and up got the crank position sensor. Sounds like a 96 engine to me.
I second that one. Anything made 2nd half of the year is the following model year.

lol I think I see where he's going with THAT one LOL
You'll have to check a bunch of things to kinda say for sure. There are a few sure fire signs that give away what year a motor COULD be, or really, are after. A 92-93 the intake has no fuel line cross over in the front area. The 95+ came with vented optispark (distributor) and if it's got steel heads then I'm not even going to start right now. I'm far too tired heh But people can finish off, and go in depth more on the tell tail signs.

Not like you want to go tearing down the motor but the 96+ LT1s had different cams also. It is possible though a late 95 could have had a 96 drive train when they were getting ready for the change over to 96 and I think some 95s came with dual cats and so forth for california which could have made it to any fbodys that was equiped with california emissions..

Hey guys; Thanks for all the input!
Here's what I know.....
- Fuel Rails crossover in the front (95+)
- Fuel lines route on the drivers side (Camaro)
- OptiSpark is vented (95+)
- Timing cover Crank Positioning Sensor (96+)
- Aluminum Heads
- Transmission MFG'd August 19, 1995.
I'm planning to install this motor into my '66 Chevelle. For the time being, I'm going to leave the bottom end and heads alone and re-seal the oil pan, intake, valve covers, rear main and head gaskets. However, I'd like to make a few more ponies by installing a different cam and perhaps some roller rockers... any ideas??
Thanks again!!!!

normal people who read left to right will know that the digit for the model year is the 10th digit from the LEFT by saying 8th digit your going to confuse people because the 8th digit is the engine code

94+ is the fuel rail cross over, not 95+. Don't know if that was a typo. Doesn't really matter I suppose. Driver size isn't limited to Camaro, Firebirds have it as well. I hope by "reseal" on the oil pan, you don't plan to use silicon. They have very nice one piece rubber gaskets you use.

By "re-seal" I mean new gaskets, not silicon sealant.
Does anyone have any thoughts on what type of Camshaft and rockers I could install into this stock block to gain some performance? Is it necessary to replace the timing chain at this time as well?
thanks

All the car scanners, even my friends $6K professional Snap-On one, reads from the Left.
Anyways, not the topic at hand.
There are many many cams that can be stuff in a stock block. Too many to go through :\ Unless you have the known mileage for the motor, and it's a very low number (under 20K miles), I'd replace the timing chain at time of cam install.

B25, just search the LT1 section for the many cam threads and you'll get an idea. The Comp grind catalog is pretty well proven around here. A member here went with a custom from Advanced Induction and was really pleased.
