You get the idea this is what they charge the public and theres a lot lot more than that they are just the main things.

If Burton do 800bhp engines for 18k I will have one tommorow.

As for 650bhp then you could get away with standard shot peened rods, standard crank, forged pistons, ported head, 509 cams/bd16's, 2wd manifold, a holset hx50 turbo, 1000cc injectors, Mike Rainbird inlet swedish, etc wouldn't cost that much.

I would personally go to NMS or Reyland.
