383 tear down, more damage than I thought Well I finally took my 383 apart because it was making a knocking noise. So this is what I found I wish I just had a bad rod. Notice anything missing in the first Pic. http://i257.photobucket.com/albums/h...1020080060.jpg This is the damage that TB screw caused http://i257.photobucket.com/albums/h...1020080070.jpg http://i257.photobucket.com/albums/h...1020080065.jpg And this is what it looked like when it was spit out. http://i257.photobucket.com/albums/h...1020080066.jpg BTW I need a stock lt1 head bad I will buy a set of stokers if someone has any. |

HOLY SHIT...i'd be pissed |
Wow thats crazy. I've seen that happen a couple of times. Are you rebuilding and just getting a new piston and head or what? I'm guessing your running forged pistons because hypos have been known to self destruct with something tiny like a screw. |
Damned, I've heard of that happening to a few motors now ... |
Was the bore hurt? Why do you want a new head? It's not that beat up. Check the gasket areas with a machinists straight edge, check the valves and seats if if theres no deform or crack run it. |

I am going to get one new piston, they were off the shelf Ross Racing Forged pistons. The bore looks fine. |
I am thinking of buying a head and cam package at the first of the year from AI or either converting to an LS1, which for some reason I just want to keep the Lt1 in the car. |
That is one of the worst feelings. It couldn't have "just" been a bearing or something, it had to go and tear everything up. Good luck getting it running. |
Holy hell, that sucks! Its crazy what things do when they get stuck insided cylinders, good luck getting it back together man. Tony. |
I never heard of such a thing happening cause of a throttle body. Hope everything works out. |
wow thats crazy, look on the bright side you have a fresh rebuild if you decided to keep it |
Ive got a set of ported stockers I'd let go pretty cheap if you want. They came off a 383 that trapped 118 in the quarter the only time I had it down there on 2.73 rear gears. I switched to a set of ported darts :-) Send me a PM if your interested. |
I have decided I am going to do a nasty NA lt1 build since I already have a mean LS1 car. I always enjoyed outrunning ls1 with cars with lt1 power. I will start with the build at the first of the year after I finish the tunning on the 99SS. |
Sweet! Glad to hear your keeping it an LT1. Sucks about that damn screw though. |
wow... of all things a throttle body screw... im sorry man thats really lame. |
