Traxxas Slash motor choice question

Ok, suppose i go with a Feigao 8L (3072Kv) on 3s li-po, and i gear it with 32 pitch Jato gear, 58/14 for a mild 39 m/h, is i'll be able to mesh the gear properly?? is the 58/14 will allow me to push the motor against the spur without interfer on the tranny case???

Thank you
