What are my options after a rod bearing failure

[Gen5snake]

Would valve work see a good amount of gains? I know my builder mentioned he has a rottler in house and usually doesn't port unless he's doing high compression large cam builds as he can get you about 80% there without a pair of CNC heads

I don't know how your combo would respond to additional valve work. I'm sure companies like PreFix/Calvo...etc. know the perfect recipe with our heads because of many hours spent on a flowbench and dyno. I'd guess that's what you're paying for when you use those guys.

According to this list, only Gen5's have Crash Data

That list is just cars using the Bosch software it appears..

This list doesnt specify brand of EDR/CDR.. but also only lists gen V

Too bad we couldn't get Mamo to possibly do some headwork. He isn't cheap but his LS Magic is strong.

Just got an update from Kevin

The engine spun #8 rod bearing. The crank is damaged but repairable. Everything else was normal wear. The other rod bearings and the main bearings were ok, not great. Not sure what caused it. It's common to lose 3-4 or 7-8. The two main journals that feed those rod pairings have an offset cross drill. We machine the crank and plug those cross drilled holes.

Everything else is ok. Just waiting for some parts.

I hate using a damaged and then repaired crank. Makes me cringe.

After looking him up, I trust him. The guy is a wizard with the motors
Still waiting on an eta, I think my headers are still getting coated
Looks like I'll be getting it back after thanksgiving

[Lawineer]

It's fine if done correctly (and depending on the damage), but I had it work out poorly for a friend way back when. It takes very little to not be perfect on crank journals to cause utter calamity.

I'm not too concerned, he stands behind it as long as I'm not using boost

He's trying to get it back to me before thanksgiving, hopefully torrie can get me around 680-700whp. I cheaped out and went with Belanger headers rather than ARH

Back in the day, one of the big crankshaft houses (don't remember which one), had a great slogan - "If it ain't broke, we can fix it".

And if it is broke, send it to Kevin

Resizing a crank journal(s) shouldnt be a problem… its the welded crank repairs that i dont think id feel comfortable with.

Many engine builders regrind Viper cranks for a smaller journal which allows them to use a better selection of connecting rods ( IE: Chevy)

Nice to see you, Dan
Anything you'd recommend adding or taking care of while the motor is out?

correct... or jsut to clean them up a bit and use oversized bearings (if they can be found). Cranks that are cracked and welded back together and then reground dont give me the warm fuzzies

I gave him the go ahead to replace the crank if necessary, looks like it just needs a cleanup
I'm more anxious about the tune than anything

Edit: I've been having issues with vividracing, I called belanger directly and Lou not only took the time to look over pictures of what I already have on the car, he made adjustments while on the phone and got me the pieces i needed. Lou, thanks again

[Mikey]

The company that processes the cranks is very far behind, so we just went ahead and replaced it
Almost there, fingers crossed that it'll be done next week

[Lawineer]

soo... why did you get a stroker?

He would have to change out the rest of the components that he already put in

[Lawineer]

How on earth did he install anything in the rotating assembly without a crankshaft? What did he do? Slide on piston rings and a wrist pin?

Shit idk, apparently he's almost done though

[Dan Cragin]

I'm running a car up to Kevin for a Motec install next week.

I will try to get some photos of the shop if anybody is interested.

He is doing a lot of Viper boat engines now, since Ilmore stopped doing them.

I'd be very interested!

Engine is finally on its way back
