it might take a littl modding but do any of you people know if this owuld fit in a rusty?

i bet you could get some serious power out of this i

its the .21 picco small block by..well ofna

no

depends on what you meen by a little moding. a little moding to one can be changing a clutch. A little moding to me means that making a new chassis and acsesories isnt out of the question. Anything is possible it is just how much work it takes to do it. heck you could put a 10 hp briggs and stratton on there and it would be possible.

i found out after a little bit that yes it does fit. someone makes a mount for it and all i need is new gears... cuz that engine will definately screw some gears over

Yes, New Era Models does make a conversion for the rustler to accept this engine. I was thinking about buying a rustler just for that purpose. I dont have any r/cs without big blocks.. :-D
