On ls1tech a guy had a cam put in his low mile Firehawk by a known tuner shop (Vengeance Racing)

After maybe 500 miles a lifter (original) failed and took the engine with it in a chain reaction.

It was no fault of the shop or the owner of the car... just one of those things that can happen.

Sounds like he had a bit of unfortunate luck. If oil and coolant leaked onto the ground, the engine is probably a paperweight. If a valve dropped, the piston could have come apart and caused the rod to fail. All we are doing is speculating until the heads come off.

There is no reason why a "first timer" couldn't put a cam in an LS1 engine. LS1howto has step-by-step instructions with pictures. Not to mention, a significant percentage of the people in C5 tech with cams put them in themselves. I'm sure most of them aren't mechanics either.

Another possibility is that the tune was off and he ran lean causing pre-detonation, which is very bad in these cars because the pistons are very brittle.

Three letters that you mentioned earlier... RPM (Real Performance Motorsports).... that is your answer... Did they tune it? have you opened it up yet? did a valve in fact drop?
I thought they went out of business because this seemed to be the "norm" with that shop..? You get what you pay for... Somebody F#$% up and did not know what they were doing. Very unfortunate! Sorry to hear it..

That was my first thought as well.

That's an okay plan, except you do not need to be WOT over 5000rpm to get to a dyno shop.

There was an RPM in Lewisville that shut down, but I think the RPM in NRH is still in business. Maybe I have it backwards.

Perhaps I am mistaken, I thought that there was a shop in NRH by that name. I think I was thinking about Xtreme....
