You have about 10 more miles. You can't predict those things. It matter how much abuse the LT1 took before you had it.

 

Opti, window motor, tranny, waterpump, and possibly headgasket will be the first to go.

 

At 190k and still going. Only thing I had to replace was a tranny and a bad cap and rotor.

 

Oh yeah forgot to mention. If it's an auto expect the tranny to go at some point. Unless you swap in an upgrade before you get there. I think they're known for going at around 100k, I know mine did. I replaced it with another with about 70k so when I get to about 130-140k I figure I'll see it going again. By then I should have my original bulletproofed and ready to go in.

 

I just hit 140,000 on my 1994 Trans AM. All i have replaced is the plug wires, plugs, water pump, and opti. My tranny went at 120,000. The engine still runs incredibly strong for as old as it is. These iron block LT1's can last forever, it's just these little accesories on the engine's that break after awhile.

 

When we had the heads off of my black one at 107K miles, there was just a tiny hint of glazing to the cylinder walls, but ALL the cross hatch was still there. And I've gone over 3K on oil changes before, and beat the crap out of my motor since owning at 84K. These things are very resilient. You just can't run low on oil or do something stupid like that.

 

if oortgot to say that i got a 160000 and im still on the factory plug wires.

 

I got mine with 61,000 miles. First oil change put synthetic in. Had to change my rear end fluid. No problems at 67,000 miles, and I drive it pretty hard.

 

Keep off the bottle and boost, and it can last forever. Tht, and routine maintanence.
