LT1 Engine Identification

not sure if this is the right place to put this, but I can't find info anywheres. I have an LT1 powered RX7 and I have to prove to the NJ DMV what year the motor is - so before I have to disasemble all the accessories off the front of the motor or try and get to the back of it - can someone point me in the right direction as to what numbers I need and where? THX

Some here:

It would be better for you to get the VIN from the donor vehicle as this would be the size of engine and registered year.
Codes are in the same place as Gen 1 SBC's.

Wink Re: LT1 Engine Identification

Actually, if the Suffix codes are still visible on the pad ( in front of the passenger side head) just post them here and one of us will decode the application date for it.

You can also find the casting date on the side of the block to give you year cast.

Re: LT1 Engine Identification

Heres what I found so far - pulled the valve covers and found -10207643 - 94-96LT1, also on in the heads were 5219 and 5250 -- managed to move a bunch of stuff and get a look at the back of the motor - all I see is 2 GM57LC
SGI
and what looks like I 115
where might the block casting number be in relation to those numbers?
From the pic's you referenced its a Camaro waterpump and a 94-97 intake, gonna try and get under the car later to see if the optispark is vented or non-vented - not quite ready to pull the accessories off the front - if there is a number what will it tell me?

Thumbs up Re: LT1 Engine Identification

So it's a Sept 11 () 1995 casting, most likely destined for a 1996 model year vehicle if this was a vehicle vs. Marine engine application originally.
So the answer to your year question is most likely 1996 ...

You really shouldn't have to "pull" anything off the front of the engine to see the pad on the front passenger side of the block - but getting a good reading of it is sometimes a whole 'nother thing ...
Since the later engines are painted black, and the paint coat can tend to be pretty thick on the flatter surfaces, you need really good light and eye-sight to get a good read on most.
I am usually successful with use of a 3~4 cell Maglight and maybe a set of magnifying glasses at worst.

The code will have several components.
1st Letter is the Engine Assembly Plant is is from - most of the mid 90s LT1 production is from the Flint (or "V" ) engine plant
2nd~5th Numbers and the month/day of assembly
Last 3 Letters/Numbers are the application suffix - or what it was originally intended to be used in/for.

To give you a quick example - my LT1 powered ski boat has a Suffix of V12075
NT.
So look for a series of numbers that follow that sequence on your engine pad.

Re: LT1 Engine Identification - Need More Help

still fighting with NJ DMV - had the car Insp. for my Reconstructed Title and he was all set to deem it a 95 - good for me because I dont have and OBD II ECM till he found some #'s that said it was a 96 (BAD for me) got the car up on a lift and found these numbers on a pad behind and up from the oil filter - looks like 612117154 - can anybody translate these numbers?
