Bigger isn't faster......

The 4.6cc has the same size housing and mounting so it must fit.

The .28 engines are made for monstertrucks. A lot of torque but no top rpm. If you can find optional gears you can get something out of it but an 1/8 onroad racer its gears is based on high rpm engines.

That is a Novarossi based engine and you can fit a new P/S set from a RX21 or 321

It is no direct fit, a TC3 needs a smallblock engine but if you are handy you can fit an 3.5cc into a TC3
