Default Bye Bye 383:(

Bad bad Saturday:( Put my L383 SC (8 psi) on the dyno and couldn't pull over 380 rwhp out of her the 1st run. All was okay from a/f and spark. No spart knock to speak of and timing was good. Just couldn't get the hp. We let it heat soak for a few and ran it again. That's when all h$$l broke loose. Took her up to 3000 rpm, waited a few and boom @#$%$. Engine is coming out as we speak for investigation. We think maybe a TRW forged piston or two on the right bank went bye..bye...no parts blew out. Were able to shut the engine down pretty quick:) My hope is that is was a defective part and not the craftsmanship going into the engine.

So anywho...I hope your day was better than mine:(

Frank :cry

Dam hate to hear that. 8lbs. should not be a problem if it as a piston maybe they will pay some for the rebuild.
I WISH YOU BETTER LUCK IN THE FUTURE

There's light at the end of the tunnel:) The engine shop pulled the heads off my 383 in front of me and to my surprise 6 of the 8 pistons went bad. I need to clear up TRW's good name. The pistons were in fact Ohio Piston Corp not TRW. It make my heart feel good knowing that TRW has never failed me:) Now as to the engine, my heads were chewed up from the metal particles breaking away from the piston and the piston compressing against the head so I don't hold much faith in keeping my heads. The engine shop is making everything good and I've been promised to pick it up this Friday:) What an AWESOME SHOP! :cheers:

My new and improved 383 is being installed as I type this. What a hassle this whole thing has been. I would love to meet the owner of Ohio Piston Company and give them the bill for this whole problem. Junk! My engine builder is at fault here too because I asked for forged pistons and didn't get it. What ever happened to a honest day's pay for a honest day's work? I watched this engine go together to ensure I was getting ross forged pistons, high quality rods, and crank. Todays a new dawn and everything is looking great once again! Car should be ready for the dyno by Friday:) One word of caution, don't put blind faith into your engine builder like me unless you have an established relationship!

Yea,
this is the C4 section and Lt1 Z28's and vettes have many things in common.
This is also a web site for corvette ENTHUISTS(sP?), not only corvette owners.
PS-
since when has there been a guest list, and who made you head of security? :nopity

:steering:

We'll put 50 miles or so on the engine today, pull the oil filter. cut it open, and take a look inside it to she how the new 383 in doing. The dyno is open today (my friend owns it) so we'll take a few easy runs and see how the a/f and timing look. Not to worry, I'll have tunercat booted up and the chip burner standing by for usage :thumbs:
