Hey guys just a few questions. I bought a dead 03 440 race chassis is there any upgrades I should do to the chassis. I picked up all the workings from a smashed 07 800r I know that the crank will need to get redone and I will through a set of pistons in it any suggestions for pistons. And I'm thinking a tra 3 seems to be better then what's on there let me know what you think
