I have a scrap motor that my buddy sold to me for 400 bucks has a blowed top end but I’m thinking of building a wild motor out of this. The motor will be on pump gas 93 octane. All engine parts will come from either HJR F.A.S.T or Redline Racine .I am thinking about getting a ported 4 mil serval or a unported 4mil cheetah cub. I’ve researching the cheetah pv setups seeing that the cheetah pv doesn’t have the light switch that the cubs do and was wondering what advantages would the cheetah pv have over the cheetah cub. I know it’ll be more expensive. And this is mostly for back road ripping or dirt road ripping.
