I've done this several times on my 350 and it looks all to similar on the 370. Just remove the strut bar, upper part of intakes, and the throttle bodies. Unclip the harness from the coilpacks and maybe some PCV hoses also. You will probably have to move parts of the harness to the side to get to the bolts holding the coilbacks in but once those bolts are out just pull the CP's out. After that's removed it's a normal business from there using a spark plug socket. Pretty easy for the avg. car guy. There's nothing really hard about removing the TB's just time.

But if you haven't done the coolant bypass mod then your going to have to remove those lines from the throttle bodies with coolant in them. Shouldn't be too much though just pin those lines back from there sources.
