my buddy has a raptor, when we race we are side by side and i then take him on top end.
does any buddy know who wins in a drag race a stock raptor or a stock banshee?????????

 

It should stay with a stock banshee if you put a cam in it, But if the Banshee has a pipe or porting forget about it the banshee will win

 

You should probably do a cam before you do the piston, a cam is going to give you more HP than a big bore piston kit will. Either do them together or do the cam, putting a cam in is alot less intrusive than removing the cylinder and performing all that work to it.
