coil pack location

Should coil packs be mounted to engine or can you put on firewall. The factory locations seem to always mount to engine

Most installations mount to engine to keep the HV lines as short as possible and to make the engine a single 'unit'. But if it makes sense for your layout and you account for torque-induced engine movement, there's no technical reason why you could not mount the coil packs to the firewall.

I put mine on the chassis rails.

I would rather the sparkplug leads flexed, than the power, earth and signal ones.

They seem to be more flexable wires.

FWIW on the Rover 200/400 series, the OEM coil was originally mounted on the passenger side front wing, behind the headlamp, with a long HT lead. On later models, they changed the design of the coil (to a more "coil pack" style although still with just a single HT lead) and put it on the back of the engine.

I guess on the back of the engine would be slightly better protection from damp/puddles, etc.
