school me on engines

[nsjames]

so I've apparently picked myself up a roller.


I need a drop in engine. Trying to keep it under $200.


I assume this one works:

I've also seen the rovan 30.5cc 4 bolts on ebay for like 180 bucks.


would like it to be drop in, but I suppose I could order carb/muffler and the like separately if that saves money, I'm just a little lost as to what the terminology is.


stuffed crank? I assume this is stroker crank.

All the CY motors will bolt right in. You will just need an exhaust and air cleaner that clears the fuel tank and servo.

A stuffed crank is where the the crank is filled in. It reduces turbulence in the case.

Here you can see what has been filled or stuffed.

is it really worth it?

seriously considering the king motor one:

I'd pick up an aftermarket air cleaner/prefilter and a 5t can and call it good.

can't swing pipe and all that at first.

Stuffed cranks increase case pressure, which in turn increases low end power.

What vehicle is the engine going into?
