I don't think so. Stock Optima/Javelin dogbones are 62.5mm from crosspin-to-crosspin. A modded Optima can handle up to about a 10T or so brushless motor, but 13.5T would be on safe side. Turbo Optimas handled Le Mans 240SB motors with over 30,000 rpm and that's no slouch of a brushed motor. However, to make an Optima handle that takes a fair bit of bulletproofing, like the belt conversion, limiter gear (Option House OT-74), hard final pinion gear (Option House OT-76, but also made by Thorp in steel) and decreasing the "punch" level in a modern ESC so you're not doing insta-backflips the minute you goose the throttle. The Optima tends to understeer on acceleration so you need to be careful unless you do other mods to address that, like widening the track width.
I did pretty much all of those mods with my Barney and CYANide project cars. Track width for the Barney car is about 1 cm wider than stock with 5mm longer aluminum suspension arms and 68.5 mm CVD joints, bigger 2.2" wheels & tires and the rest I mentioned...but I turned down the punch level quite a bit, that's with a 10.5T Tacon/Bullistorm 60A ESC combo/2S LiPo. I wouldn't dare run that on a stock Optima, especially chain-driven.
My Gold Celebration Zebra Optima is basically a Turbo Optima with chain drive but has the limiter gear and hard final pinion gear and it's running a 14T brushed motor that is just on the edge of my abillity to control...that's not saying much though, I'm no racer. It may be fun to do speed runs up and down the street, but if a car is too fast to control effectively, the fun will be short-lived when the car crashes into something.
