I have a 2006 Charger hemi 5.7, so i want to change that engine for a 6.4 Hemi, do you guys think that it will fits ok or not?

 

It will fit. Or you could do a stroker kit.

 

it will fit but that's a lot of money too drop for a new block or crate engine about 9 large from what I was looking at for that money you could fully build your 5.7 and have it be way more bad *** im talking headers exhaust throttle body intake n20 fuel rail cam maby even supercharger that's about 3 in itself

 

Where are you getting a super for 3k? I have only seen them for 6 to 7.
