As my title says, how many miles were you at when you got a rebuild? I was thinking of getting a 383 rebuild once I hit 140kish at 71k now.

well just refreshing your engine whether you stroke or not I'd say whatever mileage after 100k dependent on your current mods and goals.

I killed my original motor @86k, had a spare built block we installed that lasted to 115k, sat 20m and is now stroked. It really just depends on a few variables.

Hows it running now?

142k.

Mine started to valve float on 2 cylinders.

Called It quits with the 350.

Instead of Mild I went Wild with the 396.

146k, Head gasket took a crap and hydro locked the motor, 10 days after purchasing the car, haha. I got 0.20 over bore pistons and milled heads along with all the stuff in my sig.

I tore mine down at 104k. Engine probably just needed some bearings really. They would have been fine though, they just showed wear for 104k. Of course I wanted to proceed with my plans. On a side note, I helped a friend tear into an LS1 with 'not many miles on it.' We can't so for sure how many. It had what sounded like a rod knocking. It had a spun bearing on #1, 4 others were wiped, and the last 3 were probably ok. This was a GM shortblock so the amount of miles probably doesn't really matter--**** can happen at any time.

im currently at 187,000 miles. motor has never been rebuilt or even pulled from the car. rear end is also stock/never been rebuilt. still runs great drive it every day, but i have a 383 for it

My cadillac had 158,000 when I totalled it and put the engine in the garage. ran great until then, very strong. It will be turned into a 383, or 396 within the next 2 years, as funds allow.

The 9c1 has 180kish and is also runing strong still. But I'm whilling to bet neither of my cars were driven as hard as an F-body.

Sorry to not be 100% on topic, but felt it was close enough to be worth mentioning.

I have 156K+ miles on my Impala. It runs strong and I still get 25 mpg on the highway. These motors will last forever if they are taken care of. Even my original opti lasted till 115K+ miles. I just changed it and the water pump just for maintenance. I even have stock rear end and tranny. Tranny has zero metal in fluid.

i have 189K on the 93 and its never been rebuild... still stock with a stock M6 and rear end.... all needs to be rebuilt now... its getting alittle tired...lol..

MrCadillac

here is the quote:

"I was looking at the carnage from Joe's LT1 and I have to say I have never seen a piston & connecting rod in so many pieces. It looks like the rod broke about 1 inch below the wrist pin and took out EVERYTHING in & associated with the #6 cylinder. The cylinder wall has a chunk out of it. The exhaust valve broke in half, valve guides, both lifters bodies cracked, spring retainer, rocker arm, camshaft, windage tray & the oil pan. Luckily the cylinder head can be repaired. The combustion chamber needs to be welded and reshaped due to the large gash just under the spark plug hole. I guess when the stock powdered metal rods come apart they do it with style. The stock rod bolts lived though. "

oh man!

Mine runs like a banshee at 130k, but I worry about putting the boost to it with that old of a bottom end.

The big end of the rod was still bolted to the crankshaft. You can spin what's left of the rod on the crank. The rod broke in half just below the wrist pin and again just above the big end of the rod.
