blackfoot extreme with clod tires

[JOHN01374]

Here are some pics with the body off and one if it sitting next to my MM5700 rusty for size comparsion. I believe there is a ton of room for a 550 or larger size motor. Must be stock dia but length is not really a problem. I think I would still like to convert to dual motors like the twin Det. some day.

ydiasdad- the motor you sent the link to. Do you know if the mounting (screw) holes are in the same location as a standard 540? Will it bolt in i guess is the question.
