Just wondering, i had a thought. I would think you could, but it wouldnt be safe.

 

maybe a 25 to 45 shot

 

If it's in good shape why not? I can see if it had a knock or blow by...

My car has 150k on it, runs like it has 40k...I gonna throw a 125 shot on it eventually.

 

Seems like alot of ppl spray with high mileage LT1's, Mine has 140K as well and it's getting a NX wet 75/100 shot to it this season, as long as the motor seems strong, doesnt have any problems and you have enough fuel to supply to it..i think it will be ok. Just dont go using it 3 times a day 7 day a week, it will never last!
Check out this thread i made... Some of the stories will blow your mind!

I think it would be fine if your rings are still sealing well. I wouldnt go more then 100 shot though. I had a friend with 135K miles on an LT1 Run use it a few times, the car has 155K and still running well.

 

I wouldnt go bigger then 50 on my block.

 

Do a compression test and if the number dont range too far its all good but if they are spread apart its a definate no no

 

depends a good friend of mine had 130k on his motor. ran a 125 shot for a while then went 175 shot for a while all in a attemt to blow her which didn't happen so he took of the nos and put on a blower and that motor still is runnigng strock but he did have to replace to blown head gasket's.

 

Dont say it,Spray it!!!

 

A "lose motor" is better than a tight motor, to a point. I'd be worried about the stock rod bolts more than anything. But with that said, I'd spray it if it was mine.

Spray it!! If it goes UPGRADE , YEAH YEAH!!!
