MPG Motor Magnum vs. Hemi

Sounds like you want the 5.7, I don't blame you!
If the engine runs you $1500, that leaves $2500 from your budget.
Have you added up?
driveshaft, oil filter adapter,engine mounts,oil pan,exhaust mods,radiator,trans lines,shifter mods,electric or cable throttle pedal,wiring harness and computer mods, fuel pump and/or tank, flex plate and fasteners, A/C lines, power steering hoses, freon, coolant, ATF, oil.
What am I leaving out?
I hope you can do it for your budget.
