Yeah, Russ Merritt got two thumbs up from me! When I had one done by him it came complete. Throttle body to oil pan and water pump pulley to flex plate. This was part of the initial agreement on the build. he had to assemble it all or no build. I have pictures of the entire process too. Head and intake porting, assembly, painting, the whole nine. It was primed, plugs in, and gapped, cam sensor set, and came with a packet that covered break-in, pressure specs, basic tuning and recommended fluids. Spec sheet for all the torque specs, measurements, and part identification numbers. He has since stop doing Buicks.
