Here are the RAS rocker arms on my 470 dyno mule. I used this engine to do a lot of part testing. It was a sweet little engine, made more than 700 hp on pump gas with out of the box Trick Flow 240 heads. I think the compression was around 10:1 but I'd have to look it up. These engines usually make 600 hp with OOTB heads and pump gas compression but this engine had some "extra attention to the details" that was worth the additional 100 hp.
