lol, you should be safe now!

138,455 on my 98 Trans Am. Car was cammed earlier in its life and seen the track a few times. Never a problem

Both, I think you can start with an engine with known problems, and just do a rebuild and put good quality parts on it.

Or like the other option, 60-70 k car is nothing. make your upgrades on that and I think it should stay together for a while, remember any harder driving on anything will eventually need an overhaul eventually with upgraded parts. I think that if you have a 60 70 k engine just do some upgrades once in a while. You should be good to go.

I had 138K on mine when I sold it. Never gave me any issues at all. In fact not once did i have to replace something that broke on its own! And i drove the piss out of it!

Thanks for the all advice, guys.

if it means anything to you, ive pulled the heads off of a 195,000+ motor, and i could still see the factory crosshatch on the bores... no ridge at the top, and other then the hole in the side of the block (from a rod... someone decided to see if LS1s work underwater) it looks like a motor that was bearly broken in.. no abnormal wear on the crank or rod bearings.. the front cam bearing had a wear pattern that i see on all of the cam swaps ive seen.... but nothing bad....
if it wasnt for the fact it busted a rod out the side, id say it was a totally perfect condition motor.... and it has almost 200k on it.

at 4200 miles all lt1/ls1 blow up LOL

Seriously, I had 160K on mine and was still running good!

wow......i feel so much better about modding mine....i have 120,000 on it, and i`ve had it since it had 40,000 on it....ive kept it maintained, and really had no trouble with it....but I was worried about doing some minor modding....cool.

98K on my camed 00 Z28 and still runs great on the original trans with 3500 stall.
