on the back of the engine... GM 57LG
SGI

and on the passenger side motor mount these numbers are there: 10188334 LT1 RH

any ideas?

Engine 1

I don t know the year.....a couple closer up pics and I could probably tell......or narrow it down....I don t have a numbers book..........

The third pic.....thats the egr port that goes to the exhuast manifold.....if you reflash it.....you can just put a block off plate on there.....


Its from a cam/firebird.....

Get a close up of the tb/intake and fuel lines and I can narrow it down.......Did you get the oem exhuast? desribe the o2 sensors.....

Or get a number off one of the knock sensors

93-94 has an unvented Opti-spark. 93 also has different fuel rails and injectors along with no MAF.

95+ has a vented opti. 96-97 has a crank position sensor in the timing cover.

That should help narrow it down some.

its a 96-97, its got the crank positioning sensor...

You will want to make it a 94/5.....so you ll need an obd1 pcm for what ever trans you plan on using....4l60e or m6...if you want to go to a tv shifted trans thats possible too....

You will not use the crank position sensor....just leave it, and get 94/5 knock sensors....about $20 each....

You can get a 95 computer and have the resistance changed for the knock sensor. That's what MikeL of, then, Modern Muscle car did for mine. I kept my 96 knock sensor. I could switch between the 95 and 96 computer with out changing anything else.

Maybe MikeL could tell you where to put the resistor?

well we took the block to a machine shop and we discovered a crack in the block... but the guy i work for (who the kid bought the engine off of) is GIVING him another LT1 short block

what a deal, a long block and a short block LT1s for 300 bucks... seems pretty fair to me...
