Im hard on my truck but I know when and how to be. Plus its built to take it. I have all the goods for a decent truck build.
I'm more in the camp of.. I want to be an idiot at all times and forget about consequences, hence me going 4l80e

I had inquired about going with a built 60e, for me it was the cost. For a built 60e from a company I bought my previous 60e from, the trans was almost 4500, just the trans. A converter would be another 900 or so.
This is why I'm going to go with the 80 (eventually) plus, like tqui I want to be an idiot without a worry, haha.

If it fails get a different builder or quit driving it like an idiot.
You sir, are bang on. Driving habits and tuning both play big parts in 60e failure.

Great news, it wasn't if it was when. ... I broke my 4l60e. 4wd launch spraying it right out of the hole with 10 lbs of boost at the track. LOL. Something in the planetaries broke, caused it to lock up solid and in turn the rear spider gears broke in the Yukon duragrip. FML. I did a ford 8.8 rear end swap and then learned the trans was at fault for why the spider gears split in the gm 8.5 with the duragrip limited slip. Heck everything works till you hit second.

Case in point. .. I Drove it like an idiot. don't do what I did. So it didn't burn up, the hard parts just couldn't handle that raw torque. It made 900ft lbs of torque with a 80 shot on it. No input shaft or output failure of which is impressive. Cryo treating does wonders.

I have no doubt a 60e would last for years behind a mildly built motor. Seems like once boost is added to the equation though, it is more likely that the 60e will not last as long.

I like "spirited driving" better than "driving like an idiot", hahaha.

mega,
Do you have a build thread on your Blazer?

Choda,
What caused the explosion?

I had two that tried behind a 5.7 Vortec and it killed both.

Tig- no build thread.

My 60e held up to 20lbs of boost, it was the added torque from the small nitrous hit that killed it. I knew it would fail eventually. It made me chuckle that it held up for as long as it did. A 2wd car that's light I bet you could run 1200hp through one, and have it last If it was built right. Weight is the killer.

I will say what I have said about this many times. GM did not even feel the 4L60E would last in a 3/4 ton Express van with a 4.3 or 4.8 and used the 4L80E behind those weak stock engines in that application. My 4L60E case broke behind a mild 350 making ~350 hp and maybe 400 ft/lbs.
