Re: Project Corvette
 

woot progress!

Re: Project Corvette
 

MMMM LS GOODNESS.

Re: Project Corvette
 

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.

Re: Project Corvette
 

That sucks. :frown:

Re: Project Corvette
 

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

Re: Project Corvette
 

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

Re: Project Corvette
 

Jus shoot some brake cleaner in there, new piston and rings, then vrooom

Re: Project Corvette
 

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.

Re: Project Corvette
 

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.

Re: Project Corvette
 

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:

More carnage, bits everywhere.

Re: Project Corvette
 

Dirtybit.

Re: Project Corvette
 

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.

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.

http://monsterclutches.com/c6-corvet...eet-multi-disc

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

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.

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.

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.

Re: Project Corvette
 

$$$$$$$$$$$

Re: Project Corvette
 

Damn, that sucks about the old parts.

Re: Project Corvette
 

Ugh, that's horrible.
Sorry dude, time to drink our sorrows away?

Re: Project Corvette
 

Currently drinking the sorrow away, we should drink together soon brotato haha.

Getting excited to get it back on the road though, couple months and it will be already a year sitting in the garage, weird.

Re: Project Corvette
 

^Same for me with the BMW, a few more months = 2 years for the DSM.

Re: Project Corvette
 

That sucks, but I'm guessing you bought it with a worst case scenario in mind price-wise. Should be a lot of fun when it's done though.

Re: Project Corvette
 

Spending the coin! Should be awesome when its back together.

Re: Project Corvette
 

Yea it was bought knowing the engine could be 80-90% toast, was just hoping to get lucky haha. Didnt think it would need a new clutch being only 13k miles old. I talked to Monster and they said their C7 twin disk they pulled off a high HP car with 40k miles and still looked great. So that is promising.

Re: Project Corvette
 

Picture update. Shortblock is being assembled after they finally received all the parts, rotating assembly was balanced and the old crank was polished.

Twin Disk C7 clutch arrives tomorrow.

Re: Project Corvette
 

Nice.

Re: Project Corvette
 

Glad to see progress is being made! I'm sure you'll love the C7 twin-disc. Did you go with the OEM flywheel, or the lightweight aftermarket?

Re: Project Corvette
 

Looking good!

Re: Project Corvette
 

Went with the Standard Flywheel on not the the lightweight. Figured driving around town and what ill do with it, it made more sense.

Re: Project Corvette
 

Woot!!
One of my favorite cars of all time!
There will be wind in da grey bush in no time!

Re: Project Corvette
 

More progress! Motor is in and bolted up. I plan to work on it when I can this week, getting things slowly buttoned up. Lots of little things to do still.

Re: Project Corvette
 

badass!
The new motor is a 427ci?

Re: Project Corvette
 

Yea, the old motor was 7 Liters too, basically the same motor as before since its using the old stroker crank.

Re: Project Corvette
 

w0000000t for an engine back in the car!

Re: Project Corvette
 

:D

Re: Project Corvette
 

I can hear the bald eagles from this.
