Just out of curoisity how much work is it to put a 350X head on a 250 motor?? i know its possiable tom carlson did it for jeremy schell for the 99 season. they made it a 400 and raced it against the Rs is it bolt on?? i might do it i need some motor to use my suspension! thanks.

 

Might bolt up.. dont really know, do know that a oddsey cyl will fit a 250r, a wolverine cyl will fit a warrior... thats what I have heard, dont know if they work but very well could..

 

it won't work without extensive mods.

Its been discussed on here before.
