How Many Miles On Your LT1 ???

[Joe K. 99 Zeee!!]

I went to a speed shop the other day to see if they'd install headers on my GTP. Yes, I'm still dealing with F-body withdrawal.

Anyway, it's a real conservative shop and they won't even attempt to install the SLP knock-offs I have. We get into a conversation and I mention how I miss my '96 Z28. Surprisingly the lady says I shouldn't feel bad because the LT1's don't last.

Well, mine had over 130k when I sold it and it was running strong. I want to hear from all of you with high mileage LT1's!!

Just below 60k. Hope to have many more.

A guy I know has 290K on his LT-1 Impala SS. The motor has never been opened, but he's been though a couple transmissions. First trans was toast at 120K, the next started to slip at 200K, this one is still working. He only gets a little smoke at startup and replaces probably about a quart between oil changes.

110,000 on mine and still running strong...hoping to get many more, even with the abuse I give it haha

[Trash man]

the 95 formula i was looking to buy has 155K on it, didnt leak or burn a since drop of oil. its all on how you take care of your car.

[wolfdogs]

i don't know anymore.........

[Z Ya Later]

About 157k on the factory internal motor and orig. trans. And yes, she'll bark 2nd and chip 3rd.

[Al 96 Ram Air T/A]

Still a baby...My 96 has about 42,000

[raroZ28]

145k enjoyable miles.

Runs like a scared cheetah. Nothing is factory outside of the block and internals though.

[sneitzel]

117K, completely rebuilt 6-speed, bolt-on mods only, internals are all factory.

My motor lasted about 126k. It ran strong up until the time I spun 3 bearings. It wasn't even the motor's fault, it was the transmission not shifting until 6350 RPM (don't know why the rev limiter didn't prevent that when it was set at 5800). Prior to that, it didn't lose 1 drop of oil and ran strong.

I'm still using the stock block and a few other minor stock parts with a lot more power now, and everything's still holding strong.

[FroSSty]

I had close to 200k on my caprice when i sold it...all factory still running good. although it did need a set of valve springs.

[Joe K. 99 Zeee!!]

A lot of good examples. At the time I had mine, I worried more about the LS1's that seemed to be eating oil.

Once you know how to take care of the optispark, everything should be fine. My only major issue was the tranny going. I didn't notice the leak until it was too late.
