Carnage revealed.

Lifter dropped, destroyed the piston entirely and the cyl wall is pretty scored up. It is also missing a chunk at the bottom of the wall. Pretty sure new shortblock is needed, but ill talk to a couple shops about resleeving.

Ill take the rest apart this week and then figure out a plan.

Yeah, that does suck. Reminds me of the damage I found when I pulled my running Evo motor.

Did it take a chunk out of the bottom of the cylinder wall?

Who's/what connecting rods are in there? That one looks slightly twisted.

Re: Project Corvette
 
It has an Eagle rods/crank, Mahle pistons in it. Or had rather. lol

Something did take a chunk out of the bottom of the cyl wall. Crank might be shot too since I can see a lot of damage to the oil pan below too. Well see once I get the pan off and the motor on a stand later this week.

Resleeve is a nice idea if the crank and everything else looks ok. Saves a lot of machine work and parts costs, and that head is a stock LS3 so it's cheap to replace.

Well the motor is disassembled and will be on its way to Doug Rippie Motorsports who originally built the motor and trans.

Ill see what he can with the shortblock. The crank looks good from what I can tell, the rod bent a little bit.

I also noticed that around 4 rockers had their trunnion bearings disintegrate, so I did some research and it looks to be a not too common problem but still exists when you upgrade to a large cam and dual valve springs. Stock rockers cant take that abuse and the needle bearings fall out slowly. Not sure if this was the cause of possibly the dropped valve, maybe? Ill talk to Doug about it.

Heres one idea for that rocker issue. Seems like these fail as well, so I need to check into what rockers to go with.

Clutch was on its last leg too, so ill have to replace the disk if I can get one.

You can see the bearing totally missing in this pic:

Thats some pretty good carnage. Hopefully Doug can get you up and going relatively cheap and you can enjoy that thing a ton this summer!

Re: Project Corvette
 
Sweet carnage pics. The clutch is a monster stage 4, hopefully you can find another disc for it. Or go with a twin ;)

Re: Project Corvette
 
I wonder if the stock OEM C7 twin-disc would fit the C6? Stingray, Z51, and Z06 all use the same part #, and it's held 1200+ WHP so far.

A//// Guy 03-11-2016 11:00 AM

Re: Project Corvette
 
Interesting! hmm ill have to do more research. Stock feeling clutch would be nice. The Stage 4 is rated at 800hp I believe, but im sure its not super easy to drive.

http://www.corvetteforum.com/forums/...h-in-a-c6.html

Looks like monster makes a C7 kit for the C6.

Still havent driven a corvette lol! I should go test drive a stock one.

Kracka 03-11-2016 11:08 AM

Re: Project Corvette
 
Do it! It has a great feel and isn't a heavy pedal.

I just read that thread, seems like a great setup for the C6.

asshanson 03-11-2016 11:38 AM

Re: Project Corvette
 
Yea, it wasn't exactly a DD or traffic friendly clutch. But it was a lot better after I installed poly mounts, before that the engine was literally shaking around in the engine bay from broken mounts which made it absolutely terrible and chattery. C7 factory twin seems like a really good option.

A//// Guy 04-07-2016 10:41 AM

Re: Project Corvette
 
Welp, only recoverable item from the old motor is one good head core and the stroker crank. Block was not repairable/resleevable, all the cylinders had scoring from junk flying around and the cam was junk too.

Doug Rippie Motorsports is going to build me a new LS3 427 using the old crank. Eagle Rods and JE pistons. Compression will be lowered to 9.5 and a supercharger cam from Brian Tooley will be used. One new head will be ordered and they are going to put Ferrea solid stainless valves with Comp 921 dual valve spring kit and a trunion bearing kit for the new gm rockers too.

Still pondering on what clutch to use, but probably the LT1S from monster which is a C7 twin disk.

Already have all new fluids, so im going to swap the trans and diff fluid in the mean time and prep the engine bay for install once I get it from them. Sounds like mid May.
