We ran a photo of this bad boy in our PRI coverage and not one of you made a comment about it. We’re waiting on all the details from Racing Head Service, but from what we could see, and the little they were telling us, the engine block in the photos is the first machined casting. As you know, full race drag racing engines don’t always have cooling systems associated with them. Especially those that run on Alcohol and never have the chance to get REALLY hot. For this reason, a lot of billet blocks are built without any provisions for a cooling system. That means no water passages around cylinders, and that means unbelievably thick cylinder walls and strength. It also means that there are less ways to distort and hurt head gaskets. This means more boost and more power is possible. Hence the new RHS Solid LS Aluminum Race Block.

It’s still a casting, but without all the water passages in it. Given the fact that RHS claims that their wet block is good for 1800 Horsepower, although we have personally seen them live with much more than that being produced, we look for RHS to claim somewhere around 2500 horsepower on this new one. Again, we think it will be capable of more like 3000 horsepower, but we’ll just have to wait and see.

As you can see in the photos, this new block features the same 6 Bolt Cylinder Head bolt configuration as the standard RHS LS Aluminum Race Blocks. It also shares the same raised cam location, exterior bosses, mounts, etc. Without holding the standard RHS LS Race block up to it, we will say that it appears to have all the same features as the standard water block, other than it’s ability to hold water. The giant main caps, windage improvements, and long cylinder liners mean this one is all set to handle a big stroke crank and make big boy power. We are going to make the assumption that both standard and tall deck version of this dry block will also be available.

As soon as we know more, we’ll let you know. And if RHS will send us one we’ll build a 450+ inch bad boy with a set of twin turbos on it and see how much power we can make. Until then, check out the photo and drool. We’ll keep you posted as to when these will “Officially exist”.
