Not really. I just built an s50 for a local. I stroked it using an s52 crank and installed .5mm over 11.5: pistons,+1mm valves, dual valve springs, light head work, stock cams and it made 255whp/248wtq with a 7k redline - just doing my basic power tricks and balancing everything. Dyno tuned on the stock 413 red label. Took 2 trips to the rollers since the 17lb s50 injectors ran out at about 5500rpm, installed 21lb and went back...
