Re: Blown motors? blew a hole in the infamous #7 piston. this was in a 2k silverado with a 4.8. motor was supercharged with about 10# or so, 160 stat, ls-1 edit (factory timing). that's about it. going to 6.0 block and lunati 408 stroker kit.
Re: Blown motors? blew it at 13000. Snapped the timing chain in 3rd at 6600 rpm. Kissed all 8 pistons, bent every single valve. Collapsed a few lifters and shaved a lobe of the cam. Oh and cracked two head bolt holes on the block. I had ARE Stage1 heads milled .030 the thunder 224 cam. And every single bolt on there is. It sucked too cause I just put my moser in with 4.10's. This was in july of 2002, car still aint done as I have put another 10 grand in it. New heads, bigger cam, wilwood breaks, corbeau seats, race carpet, k-member, upper/lower a arms, etc etc. Also now I have a forged LS6 with a 3.905 bore. Nothing like a 60000 dollar POS Camaro <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" /> <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

Re: Blown motors? Shattered a rod in number 6 and part of it knocked a hole in the block. Timing chain gone as I think it was a rod bolt broke but who knows, spinning it to its max 7000 rpms.... <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Re: Blown motors? Snapped a rod in #6 and timing chain also went, spinning the engine to max 7000 rpms could have been the reason it went so fast @ 21k miles <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Blown motors? 1st motor n2o. (warrenty) 25k miles
2nd motor h/c little n2o Rod bolt broke at 6500 RPMs. It was nasty! 13k miles
3rd motor h/c 5k miles spun rod bearing
First 2 where stock replacements but the 3rd was a rebuild with aftermarket stuff exept rods.

Re: Blown motors? Oil pump let go at 35,600 miles. Destroyed bearings and crank. Rebuilt info in my sig.
And for the record, that would be GM's fault, not mine.

Re: Blown motors? 1) Spun a rod bearing with my H/C car after spraying 150 shot out of the toll plaza.
2) Snapped a timing chain and bent all the intake valves in a built 346ci motor.

Re: Blown motors? Busted a ringland off # 7 piston. 45K miles.
Aftermarket fuel pump went bad, went lean at the track spraying a dry 100 shot. Pretty gnarly looking... piston and combustion chamber looked like they were attacked by a dozen steel-beaked woodpeckers.

Re: Blown motors? Rod bolt broke at about 1000' and 6700 rpm in 3rd. The rod took out the rest of the motor, sending several bits through the side of the block. Not pretty. Its taken me awhile to get the car in a high enough priority to get a new motor, but MTI is building me a very stout 346 now. Fortunately my stupid ARE heads survived, so they will probably continue to hassle me ;-)
