If you just want to drop it in and go I would say either the RB Concepts TM523 (my fave) or the OFNA Picco .26MAXX .


Big block motors .... where do you start ? Lots of high output mills on the market today that would be more than enough in a REVO . But youre gonna have to upgrade the drivetrain or else youre gonna start stripping gears or twisting the driveshaft yokes from the extra torque . Robinson Racing makes a really nice hardened steel gear set for the REVO/TMAXX tranny that will make it bulletproof .

Me and my son both run OS .18TM's in our REVO's and his will wheelie on command , mine has the C/D , rear brake kit on it so no wheelies for me .....
