Ant - I don't realy think you even need a girdle with the 351W. Most guys that I speak to over here don't use them. I think you'd be throwing money away if you bought an SVO or Dart block.
The World of Outlaws 410 cube sprint car motors are a VERY serious motor. 800+hp, massive compression, even bigger roller camshaft and valve springs that would straighten the Leaning Tower of Pisa. Huge revs, high maintainence, etc -- but once you hear one of them at peak revs on a solo qualifying pass on a 1/2 mile oval, you'll want one for evermore..... It's always nice to dream!!!
