4.2 crank in a 4.0?

:flame: i was watchin the speed channell today and just got the last bit of a show where they were building a jeep and had a motor on the chain about to go in. did i hear them correctly when they said it was a 4.0 with a 4.2 installed. would that not make it a stroker and is that entirely possible to use a 4.2 crank in a4.o?

if so what other goodies or tricks are possible with a 4.0??

thanks much:flame:

Yes, search for "stroker" around here, you will find all sorts of discussion about this.
