The charger has a 318 in it.. but we did our best to wake it up.. with a holley 650 and some headers... we tore it apart last year because it never ran quite right and we found on of the valve springs was cracked... so we got that fixed and it runs like a sun of a gun right now.
The 440 was going to be slipped in it this year... but i bought the grand prix and im gonna be strapped for cash as it is (19 years old, going to college, you get the idea)... ill still try to put it in this year... just not with the 550 horsepower i was planing on (stock 375 isnt to shabby).
