Is it possiable to convert my 2.5 t maxx to a big block, and if so what do i need to do it? I already have a steel spur on a 2.5 transmission. Is there a motor mount made by traxxas to install a big block? I found a t-maxx big block chassis on ebay. will all the 2.5 parts fit the chassis, or do i even need the big block chassis? I've never really owned a t-maxx until recently. i have several revos, and 4 tecs. but never had a t-maxx. the spur is huge compaired to the revo, so im thinking ill get more speed out of the t-maxx. What else will i have to strenthing, or is it even possiable at all to do?
