what is high miles on a Ls1
 

How many miles is a lot for a Ls1 engine and how long can you race them on a 1/4 mile mine has 64,000

Not really any way to answer this. Mileage isn't the problem, it's wear. I engine with 50k miles could easily be in worse shape than a motor with 100K. Just depends on where/how it was driven, how it was maintained, was it ever sprayed or boosted, did someone tune it that didn't know what they were doing, etc..

64,000 is nothing as long as it wasn't beaten to death. Many people here have cars woth over 150k miles.

My 01 SS has 130K and im about to install heads and cam

My '98 Z28 has 160k+ miles and is all original and still runs strong! As long as it's not been abused and dogged without maintenance 60k miles definitely isn't something to scoff at!

64k is well below average, and doesn't even come close to fitting in the "high mileage" category for a 10 year old car.

Going off the 12,000 miles per year average my 160k miles is still a little short of average. :funny:

I picked mine up with around 65k on it almost 5 years ago, and I'm at 117k now and she runs great.

In fact, I'm just now thinking I want to get into some moreserious mods, with long tubes and a new torque converter.

153k here... Daily driven.

I pulled the 5.3L out of my yukon xl this winter due to a failing oil pump. The engine had 221,xxx miles on it. The cylinder walls still had cross hatches in them, I had the block honed and threw in a set of piston rings, lifters, oil pump, and timing chain. I REUSED :devil: the original rod and main bearings. They looked and mic'ed perfect. I have about 14,000 miles since the "rebuild" and have no doubt this truck will go 300,000 - 350,000 miles. These motors are beasts if you take care of them.

lol, i have 54,xxx mile on mine now. If thats too many miles to get into it a couple times a month im in trouble.....lol.

I think you'll be ok as long as the motor is healthy for a motor with 64,xxx miles on it.

I have 108k on mine. Broke into 11s stock internal bolton only last year and doing heads and cam very soon.

175k with some bolt ons and still running strong

Im around the 99,800 mark right now. Im planning a cake at 100,000 to celebrate.

147k here and cam sitting in my room for install at the end of the month.

I just bought a 98 z28 with 177k miles "supposedly" engine was swapped a while back but idk I'm kinda new but any way to telling if it was swapped or not?

sound like fun

my buddy has a 2001 ws6 with 160k he's been spraying it racing it for about a year now about to put a .609 lift cam and springs in it. if you do stuff right they will last its all in the tune

64k is not high miles by any means, but it's been proven time and time again that higher mileage LS based motors 90k-100k+ are capable of taking some abuse. Just take a look into the Nitrous and Forced induction sections on here. I've seen quite a few guys pick up cheap, higher mileage, 5.3, 4.8, LS1, LQ4 shortblocks and spray or boost them to the moon and they're able to take the abuse quite well.

Mine has 167k all stock supposedly rebuilt feels great good power!
