Has anyone tired to convert an 350 engine into a 250 body???

[David.Cisneros]

I just bought my IS250 not too long ago and im getting the understanding that theres really nothing you can do when it comes to increasing power. HOWEVER, I want to know has any tried putting the engine of a 350 or ISF into the body of a 250. If anyone has done that i would like to ask you more questions on what it all takes to convert the over to a bigger engine and tranny. Im really interested in wanting to do that.

SOmeone has done it, its should be plug and play, you need a new wire harness and the 350's brake+rotor
