There's a reason why a good engine builder like Wheel to Wheel and Nelson Racing are more money. Part of it is the quality of the parts used and the rest is the labor involved to check all the clearances and precise assembly.
I was told by a reliable source that the engine builder at SpeedoMotive had to assemble 2 engines a day to start to make any money. Now I have assembled several engines, and my average time is 35-40 hours to do a complete assembly if you check everything that should be checked, degree cam, verify valve train, pushrod length, valve to piston clearance, all clearances, etc. So either a place like that is giving you several days labor for free or they aren't checking and then just bolting them together assuming they're right.
