Just bought a new Dodge Challenger SE, want to do an engine swap.?

Question

The current engine is a 3.5L six--it's fast but eventually want to swap it for a 392 Hemi or the 6.1 liter Hemi. What other modifications would I have to do besides just dropping in a new engine? what is the real difference between the 392 Hemi and the 6.1? The 392 is $14,000 and the 6.1 is $7,000 but Dodge claims the 6.1 is the biggest they have offered.

Answer 1

it would have been cheaper if you to have bought the one with the hemi already in it,you,ll have to change wiring harness,s and everything,and the cost will be more than you could have got the v-8 model for,good luck.

Answer 2

You are better off purchasing a new Challenger RT or model with the Hemi.

Answer 3

Much cheaper to trade it in and get one with the engine you want. You wont have all the electrical, wiring harness, transmission, drive line issues to contend with.

Answer 4

Certainly you don't really own this car to suggest such a head-shaking endeavor.
