Try a STS D30M!! This engine will flat eat most other big blocks alive including
some higher end Italian racing engines costing $400.00 +. The power band on
this particular engine does not start to fall flat after mid range RPM's are reached
but "screams" well into the high end like smaller race .21's do. If you need a race
legal engine size STS also makes a .28 that is also a killer engine but for bashing
and bragging rights I would take the D30M hands down. This engine requires a slow
and easy 1 gallon of fuel break in, remove three head shims, start to lean that carb
toward a race tune and look out for a total beast of a powerplant!! The best part is
you can buy the engine and matching tuned pipe for around your $200.00 goal. I
highly recommend the STS #0702 tuned pipe because this motor has such radical
port timing that other pipes won't allow the full performance potential of it. TopSpeedToys
and Racernine both carry this line of engines and pipes. I paid $135.00 for the D30M and
another $45.00 for the pipe I put in my Revo from Mark over at TopSpeedToys. Check it out!!

If you are not smelling nitro fumes and listening to the sweet song your not LIVING !!
