I am currently running a OS V-spec engine in my Hot Bodies Stadium truck. The engine is tires and I am shopping for a new one.

Since Monster Trucks aren't limited to .21s, is there a dowside to running a Wasp or Sirio 28? I have also been looking at the new Picco / OFNA 27. The cost of these engines is about $190 vs $350 for a strong .21.


Can I still get the same performance with a quality Big Bore as I have from my OS . 21?

Thanks
