Engine for Cen Funfactor Rally
1. Pick a engine that have side exhaust and rotary carb. (Rear exhaust and slide carb. will need adjustments)
2. The Chassis will be able to fit engine size up to .18. We are in the process of dropping a .21 into it just to see if it fits and if any adjustment needed. Will let you know how that goes.
I assume you want a big and powerful engine in it I would say go with the Orion .18
