Default 2018 Rebuild, Maybe bigger/better, maybe not.

Well after a bit over 30k miles, 100+ 1/2 mile passes at airport events, thousands of street pulls, some interstate road trips, and getting me back and forth to work for past 6 years. Motor was purchased from Livernois on 2/15/2012. Combo was working great.
Livernois Pistons, Calles Dragonslayer 4" crank, Calles Ultra Billet Rods, all the fancy tricks they do to the LSX block, coated everything.

Last weekend, at a half mile event, was taking a passenger for a ride. Deep into 5th, around 185mph, car lost power and lost control. Was all over the place. Was able to recover and slow down enough to not crash, which was nice, but car was blowing white smoke out. Got to pits, and coolant was gone. Everything pointed to a blow headgasket.

A week later pulled one head, and all looked good. Got the other head pulls, and you could see where the head gasket failed, right into the water jacket creating a path for the coolant to just dump into the cylinder. Sadly, it looks like it sucked enough coolant in, to crack the block. Right where water jacket starts on the cylinder, there appears to be a crack. Not 100% sure, but 99.9% as I tried to clean it up, and still catch my finger, and it is right where the transition from solid iron to thinner iron where the water jacket is.

Heads are fine, and will be refreshed/inspected, and then probably sold. Initial plan is to see if crank/rods are salvagable. Pistons look fine, but I wouldn't reuse pistons personally. Cam looks perfect, lifters perfect, etc etc. So basically just a junk block from the crack in the wall.

Leaning towards maybe a Dart SHP Pro block, but it all depends on cost and what I can get. Then some All Pro or Mast heads, with probably crower rail setup. Plan would be set it up for bigger RPM. Need to contact HPR and LME to see what options they have.

WOW!!!...

Glad you and your passenger are okay. Could have been a real disaster at 185MPH!!!

Good luck with your next build. I'm sure you'll keep us posted.

Yah, spraying coolant all over the rear tires at 185 makes for a wild ride.

Thanks for the info. Your experience shows a big build can be reliable and do a lot of hard pulls. I'm glad your run ended well for you and your passenger. I look forward to following your new build.

Thanks Dave. It backs up my point that 1000+ isn't for everyone, and needs a lot more time/maintenance than normal.

Where it is now. Need to get a crane and pull block out and apart.

Not trying to be against you or to be mean but I had a feeling you were gonna crack your block after you told me (what makes you think you can hold a FI build if you canít hold a simple head and cam build) (knowing you were saying it laughing Sucks but itís all apart of the game.

Glad you got some good use out of the build and that you and your passenger are safe. Good luck with the rebuild.

Not only that, but anyone that wants to rag on it, find me another 1000+hp build that has even 1/2 this many miles, or made it past 5 years of abuse. Car lived a long hard life. Sad that head gasket failure lead to a freak failure of the block. I could sleeve that one cylinder and move on, but leaning towards bigger/better/badder.

Right now got to get ahold of HPR and LME and see what options are. Thinking LS next, Mast heads, crower rockers with a solid roller. Something to turn big RPM. If crank is hurt, maybe downsize motor to something like a 388-390.

Glad to hear it wasn't worse Nick. Could easily have ended a different way. Nice job saving her. That motor held up far longer than I would ever expect, especially because you drive it regularly and race it.

Why the LS next block? Seems like that lsx block served you well.

Cost, and like some of the options it has.

Other options are LSR block but damn it is bling bling. Was thinking Dart SHP pro.

Headgasket was the LSX 6 bolt head gaskets. At the time 6+ years ago, that was the only option for a 6 bolt head gasket.

That being said, only 50/50 if it is actually cracked. Just a little line there that I can feel with finger nail. Could be from piston ring, or who knows. Need to get it out and see. A quick hone and it maybe fine. If it is a small crack, can have that sleeved easy enough and I'll keep the block for another project. Sleeve that one hole, bore it to 4.155 and do a basic n/a grunt motor to throw into a truck or my jeep.

Ouch.... Well, at least you have a story to tell your grandkids someday. They'll think their grandpa is a badass.

Might as well give LSM a call while you're block shopping. I've used a couple of their billet blocks, and they are works of art.

Were you using studs? I assume so.....
