Here are the parts and labor I was looking into for the engine build but was 2 far out of my price range. I only need 400HP max
Adjustable cam sprockets 105/105, 168
Hayabusa Cam Chain 72.00
Engine and case studs 159+89
New bearings throughout motor 200
Cut Tranny, 250
HD Billet Output Shaft, 350
Crank Case lightening, 250
Headporting, 1mm over stainless steel exhaust valves 1295+139
Cams(probley want be adding them)
Labor 1500-?
If you are on a budget I would drop the crank case lightening, head porting and oversize valves, and cams..
If you just want 350-400whp it's not really needed IMO.
