Competition Motor Pic's

[BigBadDodge]

Well the BBD left here last Monday afternoon, arrived in New York last Thursday afternoon the guy must have been flying



Joe started it right up and new it wasn't good so he took the head off Thursday night and just sent me these pictures he said the the head is still good so that's good piece of news for him. I knew the the block was going to be toast.

Was something wrong with those parts? I still haven't sent you the $$$ I will when I get the check book from the wife.

 

[zstroken]

Just one cylinder messed up?? Were the others in good shape?

 

[jwilliams3]

Scott,

In your ebay ad you made it sound like all anyone had to do was replace a rod and they were good to go!! :-laf :-laf

Kinda downplayed the catastrophic failure part huh?

 

[bgilbert]

Expensive parts truck:-laf.

 

[9 Lives]

I have a block for sale cheap... .

 

[Jetpilot]

We are starting to see and hear about more major carnage then we have in the past due to more and more HP from these engines..... I have seen several street engines that were pretty much destoyed in just the past 3 months! Several years ago 500 HP was a big deal, now its nothing. Heck you can go to a big dyno event and nobody even notices 600 anymore you have to make the jump to 700-800 for folks to take notice. With HP going up and up I suspect we are going to more and more major breakage.

Doug what failures are you seeing? Are these 800HP street trucks? Or are they seeing issues at say 600HP?? Also are they high mileage engines? I know some people who want a 600HP truck and they still think they should maintain it like a 215HP truck. LOL

 

[Jim Fulmer]

How about blocks, pistons, valves, cams snapping, heck you name it! I'm now in the cam group.



No kidding on the 600 hp, heck mine will do that with 370's on #2, add a little N2O and your at 800... ... like it's nothing!

[Signal73]

what does he (or you) think caused that? Bad injector, or just big HP wear+tear

 

[Jim Fulmer]

I'm thinking Hydraulic'd cylinder at high RPM. The rod looks bent or is it just me, so no rod failure and there is a hole in the block..... path of least resistance, then the piston cratered.

Jim pretty much hit it..... The engines are not high mileage motors, but rather just turned up engines. Heat and pressure takes a toll on our engines. These engines are tough but not indestructable.

 

[Pat@BD]

I think we are definately starting to find the limits of the blocks and rods, well basically the bottom end of these motors. They were bullet proof for up to 600hp, but now that numbers are approaching and even exceeding 1000hp we are going to have to seem some more custom parts for these motors to be able to hang in. I remember my first dyno day here at BD over 6 years ago and 425hp took top honours.

Scott,

Never down played it, perhaps you read wrong:



"Currently this motor isn’t running as we did some lower end damage late this season probably a rod, piston, or block damage, hence the low reserve as we have taken into consideration the fact that the buyer will need a short block it’s a $20K motor and can be up and running again for a relatively small price. "



Actully I think it's in better shape then I would have thought if you had heard it runing. And like I said take the motor out of the equation and its still a deal ands a half



Jim, I am hearing just the one cylinder, and all else looks like normal wear and tear on a four year old motor



BBD

 

[Graphic man]

4 years on a motor running hard like that... ... i think you did pretty good !!!!!!!!!



i use to pull the motor in my 66 prostreet chevy 2 if it had more then 5-8% leakage :-laf

 

[ChrisOlson]

how much hp were you running on the dyno, and what were you doing when this happened BBD



chris

 

[Gary - K7GLD]

There is probably more peripheral block damage than evident in those photos, but if not, wonder if sleeving it would save the block?



Probably not for a competition engine, but maybe for less aggressive use.



But, pretty good possibility of warpage and other ills if you look closer - main bearing web distrotion, etc... .

 

[JGheen]

Looks to me like EGTs took a toll on that piston, melted it and then once the piston was pretty much gone, the rod broke through the sleeve. Overall very impressive how long that engine lasted with how hard it was pushed. PDR builds quality goods.

Heck we are filling the blocks with cement (mod trucks) and they are still brakeing.
