Ok I bought a blaster with an early to mid 70s Dt 400 in it. My question is can I swap the topend off of a say early to mid 80s yz 400 on to it. I want to build it as a high comp big bore 400 with a port and polish but can't find pistons or rods for the dt 400 and honestly I would like to do away with the comp reelease that's on the motor now.
