PRW Aluminum Shaft Mount Rocker Arm System

Here is what I have. Built by Hughes Engines, has their modified drilled out oil galleys.
Eagle rods, pistons and rings from Diamond Racing compression is 10.7:1,, Edlebrock RPM heads. Has a Hughes hydraulic cam # HE4650 with their lifters. Cam specs. .606 intake and .614 exhaust , Hughes double valve springs with 1.6 ratio rockers.

I'm planning on calling Hughes on Friday for more information and help.

So the whole motor was built by Hughes?

If so, did they build just the long block or carb plate to oil pan?
