4.5+ engines in a T-MAXX

DOES ANYBODY OUT THERE RUN A BIGBLOCK (4.5+) ENGINE IN THERE T-MAXX?
IF SO, HOW HARD TO INSTALL, AND CAN IT BE USED WITH THE TRAXXAS STARTER SYSTEM.
THANKS!

4.5+ OR (.28+)

u can put one in the t-maxx but u have to buy a conversion kit if u look at my t-maxx it has the conversion kit and a big block .26 http://www.horizonhobby.com/Products/Default.aspx?ProdID=DYN7403 thats the link to the one i got its fairly easy to put in but u cant use the starter with ne big block i dont think i believe u have to use a pull start or starter box
