Hey guys,
I'm wanting to know what would be the best engine for an sc8 the most ill spend for one is 400$$

No so sure about a 28 sized engine and if that is an option for me it would have to be a bump box engine.. but I'm thinking a 21 or 25 or even a 26 but im not sure if they and bump box 26 sized engine. Thanks all..

P.s will a 21 have enough power to push a sc8 around?? Like a werks b6 pro?? Thanks again all..
