We have several engine builds that are about to start here at BangShift, and they will range from 400+ to over 1000 horsepower, but every time we talk engines we can’t seem to get the super bitchin RHS LS Aluminum Race Block out of our heads. If we got out hands on one, we’d love to build a 500 inch, high compression, nitrous huffing, screamer. But then we’d also like to build something in the 430 inch range with a set of twin turbos on it and go for big power too. What to do, what to do? This is the ultimate “What would you do if…?” LS engine question.
If you won the lottery tomorrow and were going to build a bad ass LS engine using the RHS block as the foundation, what would you do?
With cranks available from just about everyone, and cylinder heads that flow to the moon and back, there isn’t much you couldn’t dream up and make a reality if you have the bucks. The cool thing with turbos is that in theory you can make a ton of power with relatively low compression and drive the snot out of it. The cool thing about tons of compression and all the spray you can throw at it is, well… tons of compression and spray. LOL
We want to know what you would do. Not that we’re expecting Santa to bring us one of these things, but if a shipping crate happens to fall of the RHS truck on it’s way out of SEMA, it would be really really rude of us not to do something great with it. Ha!

So, if you had an RHS LS Aluminum Race Block, what would you build it into?
It’s really simple and am in the design stages already. Turbo motor with twins. Thinking something along the lines of twin GTX47’s or GTX55’s. Will be put into a custom built round tube AWD chassis with a Factory Five ’33 body placed on top of it.
Currently at the beginning stages of laying out the chassis in Solidworks. As I get a little further into the design I’ll be starting an updated build log.
I’d sell it and build a Ford.
When a Hellion turbo kit can punch out over 1,200 h.p. on a FRPP Coyote Aluminator crate mill, and with turbocharged CHI-head SBFs and Kaase BBF’s hitting it ever harder, who needs a LESS.
501 cubic inch naturally aspirated using the 4.165″ bore & 4.600″ stroke
Run E85, high compression, huge cam, and a C6.R style intake
450ish cubic inch ARIAS HEMI headed individual runner twin front mounted chassis works supercharged monster.
I’d order a set of Edelbrock canted valve heads from EFD-Curtis Boggs, add the appropriate equipment and drop it in a front engine dragster and see if it could run with the Champion Speed Shop fueler. Everything else has been done already.
Keep having dreams of this; a 500+ inch with twin sequential turbos feeding a set of Weber ITBs.
I would go for max displacement, low compression with a twin turbo setup, then drop it in my 66 Olds Dynamic 88 convertible. Pump gas all the way, six speed auto gear box, dress it to look like an Olds motor.
