Snap goes the crankshaft. The mains are all intact, rods banged up but all intact as well.

Wow that thing is destroyed. What RPM were you turning when it let loose?

Over 5500 top of 4th at VIR on the back straight. It's my father's car and he was driving. My car is in my avatar.

Wow, im at a lost of words. But that Panoz is a very interesting car.

Finally got the chassis completely stripped. Ready for a power-washing then going to do some welding and then off to the powdercoater.

Yike, any fire associated with that? Glad he is ok.

No fire... not a very dramatic death. Just a thud then nothing. No warning, oil pressure was fine.

I see it as a blank canvas... can't wait to get it all purtied up in shiny white powdercoat.

Chassis degreased and powerwashed. Doesn't look like much but getting all the adhesive residue from the old heat insulation on the tub was a chore. Time for welding. Going to weld up all the holes from the rivets that held on the old heat insulation panels, weld in a proper harness bar, and relocate the steering column a little etc.

I can't recall ever seeing an engine come apart like that. The chassis is looking good, can't wait to see it powdercoated.

That is a lot of carnage on that crank. Looking forward to see this come together

Been doing lots of welding getting it ready for powdercoat. Lots of old rivet holes... about 2/3rds done. Plus more parts have come in.






Fortes plugs for the speedometer sensors. The driver's side is the mechanical gauge port and the passenger side is for electronic (If you haven't figured it out... not running a speedometer).



Powermaster 1-wire mini racing alternator with mount kit for a Ford 9"... still have to work on pulley alignment.

When I owned my machine shop I witnessed a few similar failures in SBF road race applications using solid mounts. At first we saw the freeze plugs fall out then the blocks split. I believe that a combination of solid engine mounts and a cushioned trans mount, along with a bit of chassis flex was the culprit. The ford block is just not rigid enough in that area. I have not seen the same result in a drag car until you hit about 600 hp, then they split down the main line.

FWIW we didn't use any solid mounts in our application. Stock rubber mounts on the engine and trans actually. Putting poly stuff in with the LS1 swap.

Replaced the LS1 springs with GMPP LS6/2/3 springs and installed Smith Brothers restricted flow pushrods... shiny new stuff...

Took a break from welding and got a fair amount done on the engine. Time to take a break and tear into the Z06 to replace the cam/lifters in prep for October's VIR event.

Horsefly that flew into one of the oil returns in the head when doing the springs. Found dead on top of the windage tray.


Later LS1 blocks are apparently drilled for LS2 chain dampers. Amazingly the local Chevy dealer had one in stock so I could move forward putting stuff back together.


Custom pickup that comes with the new pan hooked up to a LS4 high volume oil pump.


Kevko pan installed.


Timing cover and ATI damper hub installed.


Hub pinned.


Water pump heater core/pressure tank ports threaded and plugged.


Drilled and tapped the Edelbrock valley cover for another crankcase vent port (comes with a boss for doing this). Still have to get a 1/4 NPT to 3/8 hose barb to thread into the elbow.


Starting to look like an engine again.
