hi guys, I see this forum has been dead for a while but i need to know the dimensions of the bs 34cc motor. I am building a 1/5 waco and i want to put the motor IN the cowl (get the idea)?? the cowl is 8inches in diameter and i have 6 inces firewall to the back of the prop flange. i want to keep cutting to a minimum

also can these motors run inverted? ideally i would like an inverted install

thanks
