What's the room that is insulated, in the right rear corner of the shop? Is that a walk in cooler?

Ed, you think getting it out with the winch in place was fun? Just wait until you put it back in.

You can't really see it in the pictures, but most of the number 6 piston is in the bottom of the pan. I want to get the rod bolts tested for hardness, anyone have a recommendation as to where to send them?

i got a coworker that builds engines i will ask him where he gets rod bolts tested i think he has the tool for doing them . other than that i know he measures the threads and lenght to see if they have stretched

For what it's work, when I pull these powerpacks I take the air cleaner housing off and at least one fender, both if the bolts come free. This along with the winch. Makes it pretty much easy. For me its much worth the effort.

Well, the motor is going back in by itself, the tranny will go in from below. I need to know the approved method for eliminating the manifold flame heater, I have ether start, so I want to get rid of one more thing that potentially leaks fuel, especially on a hot turbo. . .

The dead motor is stored temporarily in the back of the M35A2 dead carcass carrier. . . :p

It looks like the rod bolts failed, the crank smacked the dangling rod, ripped it out of the piston, and then ejected the rod out the drivers side of the engine block. The piston is at the top of the bore, the rod cap and some small pieces of piston are in the pan. The crank is damaged beyond repair, not sure about the cam, but it's right there with a courtside wiew of the carnage that happened. . . but the side of the cam I can see isn't scratched, maybe I'll get lucky!

The either kit comes with an 1/8" or 3/8"(can't remember) pipe plug for the fuel supply at the bottom of the IP and for the return line, you simply replace the tee'd line(center return line between injectors) with a new straight piece of 1/4" fuel line(DOT air brake line is a good substitute) Be sure to use tubing end inserts and new ferrules(standard brass ferrules work fine).

My money says that the remains of the piston are still residing in the cylinder liner.

With this engine using an offset connecting rod cap, it appears that one rod bolt failed liberating the connecting rod, which was in the way when the crankshaft continued rotating. The crankshaft struck the connecting rod and forced it out the side of the block. http://www.steelsoldiers.com/attachments/deuce/155043d1259437900t-55mph-detonation-carnage-002.jpg

The rod bolt as you stated probably was over torqued and stretched. Spinning four plus pounds of piston/connecting rod at 2500 rpm for long periods of time is a recipe for failure.
I think I called this back when you first posted pictures of the event.

The cylinder liner being steel is much stronger than the cast iron engine block.

I had a 582 cubic inch Chevy come apart at around 8,000 rpm. The only things salvagable were the water pump and one valve cover. The two connecting rods came thru the sides of the block but the cylinders liner stayed intact.

I'm interested in seeing the results of the knoop hardness of the rod bolts and any measurements you make on thread deformation.

Here are some more pics, I forgot about the smashed airlines and such in the chassis, so the motor did not go in today. . . :cry:

Some pics of the spin on install, and the pyro install, along with the manifold flame heater elimination. . .
