sooo ahhhh, the best big block mount on the market hands down is the qoncepts kit. i broke the traxxas kit waaayy too fast! and the new era kit, well, look at it. do ya see how much leverage it gives the motor against the chassis? its gonna bend chassis like crazy if you bash with it.
i just tryin to help ya man, once your chassis tweaks just a little it will start eating spur gears everytime ya start it... and it wont be obvious its bent either.
been there done that.
