I'm looking to do a motor swap in my 02 Mirage and I found a (what the guy says is) a 420a motor (acidentally put the long block in, was reading a blog on the internet--nm lol) It looks to me like a 4g63 motor though. I was wondering if anyone could tell me the truth and if it would be possible to put it in my car without mods to the motor mounts, etc

Well The picture engine is a 4G63T and not a 420A. the 420A is a Chrysler engine and i would not put it in the Mirage at all , the build quality is not high on that engine and the structurale top and bottom end is not as high as a build strength as a 4G6 series. id rather go with a 4G64 frum a US 99-01 Galant ,

K thanks dude...I'll keep that in mind.
