depends on a lots of variables, what valve covers are you using? if your using stage 5 covers the passenger side will be right on the shock tower, you will need to massage that area for clearence, what exhaust will you be running, ttis work very good,the arruzza mounts work very well in a 440 k frame, but they are solid on one side so you will get a slight vibration not much but a little, you will need to install a milidon flexible dipstick and tube BEFORE you drop the motor in, you will also want to run the mini starter, and are you running a auto or manual trans? you will also need a 3 speed wiper motor to clear the air cleaner, also if you have power brakes your brake booster wont clear the valve covers on the hemi either, list the details of your project and we can help you better
