PQ:
I don't mean to act like I am a know it all here, but as I just went through a very similar upgrade on my car, I noticed something in your parts list.
With that maggie (and 3.2" pulley) with that cam, you may need to upgrade your fuel system (unless I missed something). The injectors that came with my maggie were not big enough once my cam went in (They would have been over 90% duty cycles). So, I upgraded to 65# injectors.

I also had a dual fuel hat installed when my cam went in.. I wasn't comfortable with the stock fuel pump and BAP.

You are going to be making more boost than I am (I'm at 8.5 lbs) because I have a 3.4" pulley and you are going with a 3.2"

Running out of fuel with a maggie can be disastrous. I was adamant with the shop about over doing the fuel system.

I am glad to know about it now though because I was planning to forge the motor anyway. I need to get a complete list of exactly what I need to have them replace. They did a lot of parts when they did the cam, but I don't want to miss anything when they forge the engine. That will happen next winter.

my 'three' little things are the oil pump, timing chain tensioner, and the timing chain....just cause that's what I had to deal with.

I saw the dogbone dampner on another pic of your build...so have you swapped to a C5R chain yet?

Make sure to ask Charlie for the sticker!

I was sorry to hear about your experience a couple of weeks ago...well...sorry and shocked. Glad to see things are back on the right track...I'm sure you'll be happy with the results...

I feel like I should scan my invoices from IPS so you can see what you think of the parts list (it's rather long!). Then you can make me a laundry list for when they forge the motor.

Ooops. Did we just threadjack hugger's thread? Sorry!

Not me! You've got my whole list! But I love the idea of sharing 'lists'...and I'm sure Hugger won't mind seeing a good list as he preps for 're-birth'....

Just kidding

This thread is meant to be informative....I'm 99.9999% sure it's doing it's job.

Sorry to hear and see.:( Apologize as having not read every post. How big is the Cam? Are the pistons stock. Could there have been a clearance issue? Remember reading an article in CamaroNow about Cams and heads on the LS3(just found the article again now) The build team went with a .617/.624 231/239 113d Comp Cam. They claim any wilder and there can be clearance issues with the factory flat tops.
Still trying to decide whether to go with a Cam or put the money towards a SC. Brings back memories. The 82PaceCar I had came with a weak 305. Cam had a plastic gear that self destructed while going to work in the early AM (think we only had 12k warranties back then. Whatever it was,no coverage:() Left it by the side of the road in a puddle of oil and hitchhiked. It came back better than ever at the time with a 406. Hope you are back on the road better than ever asap

So, you modded it?

actually is a good point, i know my local shop is very big with making sure there is clearance, they wont even put the cam into a car before putting the cam into a test engine first to make sure they can see everything is going to work.

I'm still sticking to my original theory of not having enough piston to valve clearance. The ls3 engines have no valve reliefs. So cam selection is important. And just because the same cam worked in your buddies car doesn't mean it'll be ok in yours. I learned that lesson building a 4 wheeler engine. I'm imagining that your shop, huggerorange, has installed this same cam and had no issues. So valve clearance wasn't actually checked and here you are left holding the bag. Why did it take so long? Well my guess is you had less than the minimum clearance required and when you ran the car hard you had ever so slight contact. Then the springs got some miles on them. Things got worse. And then you know the rest of the story.

I don't own a shop. I've build lots of engines though. From go-kart to lawn mower to atv to stock automobile engines to the pretty powerful engine in my former third gen. I had failures. I've learned from my mistakes. I now know what it takes to build a reliable engine. The most important thing is to check, check and recheck your clearances. I'm anxious to see if you cam pin broke and caused this. If that happened, well I could be wrong or the above I mentioned happened and help push that along. I guess we shall see.

Going into the internals of the engine and swapping out parts just puts more pressure on the system. So the OEM parts that had problems in the first place (cough*lifters*cough) may break sooner than say if the car was left stock.

Once again. Modding does NOT kill engines.

Where have i heard that before? LOL

The only oil pumps I have see fail have been 100K+ mile pumps and one BRAND NEW ported pump.

The type of problem you are describing would slightly bed a valve or two, not cause all this.

NGK TR6 plugs have the tips protruding.. NGK 7IX or NGK 8IX is cooler and the tips are flush.. With your blower you might want to go with the cooler tips for added safety.. Stocks are iridium and you want as cool as you can run to avoid preiignition.... One temp range for every 75 to 100 HP.....just sayin
