Regardless of all the extra work, it costs a lot of actual money (excepting VW low HP stuff). I can do this easily: 1) 320 core, $3k. 2) Case, crank, cam, tappets, bearings $1500. 3) Cylinders +10 to stud assembly $1000. 4) Valves, keepers, rockers redone, rods redone, gasket set $1250. 5) misc bolts, nuts, etc $100. Total under $7k for 2000 hours of dependable 160HP. Find me a car engine that will even come close.
