Lb7. Blown head gasket

[Vmyrhaug]

Victory reinz wave stopper mls gasket. Is that the correct one too use?

 

[Bdsankey]

Yes, the Mahle Wave Stopper is arguably the best MLS gasket we have available for these trucks. Make sure you take the heads to the machine shop and have them decked for flatness and have all the seats/guides checked as well as checked for cracks and valve recession after decking.

thanks
of coarse the head will be checked and resurfaced.

victory reinz and mahle is no difference?

 

[Vmyrhaug]

google made my answer. victory reinz is mahle
will be arp studs, and maybee i drop the oilpan and install street rods also...

How much power you pushing? I’m not far enough along to justify aftermarket springs, but I did have them raise the seat pressure. I also install a ATI dampener.

For now only 350-400whp. But future with build trans goal is 600whp. I think its possible without build everything. Also going to buy sac45 inj. I think they will be perfect for 600whp. For now stock turbo. Will be ported, when it blows up an upgraded one, maybe compound.. it's my dd, no plan in going crazy in build.

There are plenty of drop in turbos that will get that 650 rwhp cheaper than rebuild and modifying a stocker.

IMO at 600 WHP you are pushing it with stock LB7 rods, even with a turbo and SAC45s. It can be done, and has been done, but your tuning needs to be spot on to keep it alive long term. I run the Victor Reinz / Mahle wave stoppers in my LB7 at 660+ WHP, never had an issue. Definitely the gasket to use on a LB7.

Plan is too install street rods. They should be good for 1000hp. I'm going too pull out engine for this.

Street rods are a solid choice for ~1000whp.

How much hp on stock cp3?
How much on on sportsmann cp3?
What is the best cp3 choice?

 

[Bdsankey]

How much hp on stock cp3? ~575-600 if it's healthy, some make a touch more
How much on on sportsmann cp3? ~650-675 it seems (my experience, some may have gone further)
What is the best cp3 choice? IMO for your goals I would go with a 10mm CP3 from Exergy/Fleece/S&S/Industrial.
