Just talked with DFS68 Charger, anyone want a never started 440?

[cudaken]

 God, at this point I do not want to start my 440 after talking with DFS68. I did the body paint work on Daves 68 Charger. While we where at it Dave decide to do some work on his great running stock and fresh 383. After I yanked the 383 so I could do the bay Dave opened up the 383. Installed 906 Heads by Huges (that is a story in it own right) second set where good and had oversizes vales and port work, Huges cam, really F--ked up timing chain that took 8 hour's to degree in, Hughes Roller Rockers, MP intake and after fighting with me TTI Headers.

We started the Engine her at the house and I broke in the cam. For not being dialed in it ran great. With 2.76 and 30 MPH roll it would get rubber.

Dave took Goldie home then things started to go bad for him and Goldie. 383 started to back fire at idel? Dave checked the vale lash and found Huges had double shimmed the vale's and they has sliped out from each other? Like I said, won't go into details about Dave dealing's with Huges but I will never use them.

Dave took the Heads to INDY Cylinder head for needed repairs. Well to day Dave installed the heads, BUT he found another problem, cam is worn flat on some of the lop's! Ones with bad shim's.

God I feel bad for him.

Guess that is one of the many reason I am dragging my feet on firing my 440. I have $12,000.00 sitting in front of me. Cannot break it if I never start it.        

Well I would say I will bite the bullet Sunday, but with the tooth I need pulled I will say gum the bullet Sunday and yank the Huffer and break in the 440.           

                                                     Cuda Ken, afraid to fire it again.

Can understand the feeling when you just saw what happend to the other guy, but its better to end the pain right away and start it...

GO FOR IT kEN! you gotta make room for Telvis anyhow!

Dave real sorry to here about your Lump! Whats your game plan now?

[DFS68_Charger]

Thought I was going to fire up the 383 this weekend until I pulled a lifter out of one of the bores. It had a small chip out of the flat that may have been there from the get go. I was'nt going to take any chances and run it; the cam lobe looked fine. Just to make sure all was well I started checking all the lifters, pulled one out of the No. 3 hole and found the flat was dished . --Not good. Put some light on the subject and found that the cam lobe was wiped out---looked good if it would have been a roller profile.
I'm going to pull the cam out tomorrow and toss it in the trash along with the lifters. I don't have a game plan beyond that.
I still have the cam and lifters that I pulled out originally, but don't want to reinstall with the setup I currently have; valve springs are probably too mean for the stock stuff.
Probably going to go will a custom grind, I dont know. Will have to have a couple of CAM2's and sleep on it.

 Dave, like I said you can have the MP stick for free. It would have used the MP Spring P3690933, it's lift range is .440/.510. As far as vacume, well that you would need to ask Neil about.

Talk to the folks at Indy Cylinder Head's and see what they have. Good part about them if there is a problem you can bitch at them in person.

Sorry to hear about the problems.   All these cam failures are quite alarming....yours is one of many that i'm aware of. A buddy wiped two MP solid cams last fall. That brings me to the other issue ; metal filings all through the engine. If it were mine, i'd be pulling it and checking everything. In my friends case, the bearings were wasted as was the oil pump. The cylinders needed to be re-honed and new rings were installed at the same time. Crank was turned .010 with fresh bearings as well.

As a bare minimum, pull the oil pump and disassemble for inspection...have a look at the rotors for signs of damage. Cut the oil filter apart and see what's inside. It wouldn't hurt to drop the pan and inspect some main and rod bearings while you're at it. Good luck Dave.

Ps. Ken, for the breakin use Shell Rotella 15-40 diesel oil and a can of GM EOS (engine oil suppliment). As soon as the cam is broken in , drain everything off and replace the oil and filter to purge the motor of assembly lube and small metal particles that break off during the normal breakin procedure. We did this with Dave's (the Arrow) engine and so far so good.

Sorry to hear about the problems. I hope the damage is minimal, good luck !

Ron,

Thanks for the advice. After a few CAM2's and sleeping on it. My thoughts today turned to the issue of the metal in the motor, bearings, etc...
I caught this cam failure very early. Probably more metal from the lifter is missing than from the cam lobe. I almost did'nt catch it when I pulled the lifter out.
I will probably do all of the above that you suggested. Easy stuff first; oil pump and filter. The cylinder bores look good, but that does really meen all is well. Going to have to look at a couple bearings.

I hate to have to tear into that far, but it will be for the better. I've got a buddy that races roundy rounds. He burned a piston all the way down to the top ring. Replaced the piston and rings and went for it. It blew up (understated) at 7300 RPM. I think we were able to reuse the intake from that motor.

The cam that got munched was a Hughes 2328BL. Hughes did the head work (Satge 1 Port), springs matched to the cam, their lifters and roller rockers. Everything seemed fine after break in. Motor developed a little miss with a slight pop in the exhaust. Pulled a couple spark plugs and indication was very rich. Pulled a valve cover and noticed that I had valve shims that had slipped out of place and thought this was the cause for the miss. Pulled the heads and took them to Indy Cylinder. They could'nt believe that Hughes was responsible for the Shim work. ("They know better than that") was the response. The springs had a minimum of two shims under them and some had three. The springs that had three were the ones that were slipping and the cam lobe that got wiped had a slipped shim.

Indy machined the heads and installed spring cups. Found the cam prob right after bolting the fresh heads back on.
