Rhs Ls Block

[COYBILT]

Hello everyone,
Just curious if anyone is using the RHS block and how they have liked it. We are currently looking at one and all the features seem to be perfect, but i want to see how everyone has liked the block. Is anyone here making 900-1200 hp with one of these blocks and are you doing sustained WOT with it.

I have one in my car right now. So far it's met my expectations, make sure you seal the head studs, they're known to leak water through them if you don't. We have one at the shop that made a 1,000 hp with a Whipple on it, it's had some seriously hard pulls on the dyno with no issues. The plan for that one is to have a road course capable 1,000 hp without serious heat soak issues.

Good solid blocks. As said seal the head bolts

I have one, but it's still in the box. LOL!! No WOT with it as it's just a street car, but I'll be mating a supercharger to mine, so thanks for the heads up on sealing the head studs guys.

Thanks for some of the input, we are looking to beat the hell out of this thing. This engine block will be subjected to silver state classic and as we all know that is a pure torture test.
