2.7 to 3.6 engine swap
 

Is it possible to fit the new 3.6 engine in an 04 Concord lx ?

a 3,6 penastar motor or a 3.5?

The 3.6 penastar is the engine I want to swap into an 04 concord that currently has the 2.7 liter engine

good luck with that one hope u have alot of money

Do you know if the 3.6 will drop in the Concord engine bay, fit under the hood and bolt up to the concord transmission or would I need a different transmission too?

Yes, you'll need a trans. That engine is worth more than 5 of those cars.

U may get the mechanics to work but after that U get to build from scratch some one the network of computers needed to run that things need a CAN bus system which U don't have an on 04 Concorde

Are you attempting to make an SRT type Concorde or just want more power? A 3.2 would probably be the best and cheapest way to get more power.
