LD4B OR LD340 FOR 273?? Coil mount?? Need pics

Mulling some ideas around here....Dad n I always wanted to put a LD4B on his 273, BUT we didnt like the thoughts of mounting coil on firewall or inner fender. We like the stock look, so we always stuck with the stock cast iron 4bbl carb.

I dont know why, but I never thought about my LD340, its just sitting in my shop on the shelf. It has provision for choke and for mounting the coil.

Here are specs on engine as it is now

Comp cams kit with 270-s cam n lifters, 901-16 springs, comp dbl roller timing chain
Eddy 1405, but we got elec choke for it.
Torque converter is new approx 2800(not sure of stall tho)

Is the LD340 usable on Dads 66 date coded 273??

OR has anyone got pics of an LD4B bolted on and where did they mount coil.

Im thinking that maybe I could make a coil mount that utilizes the 2 rear carb studs? Anyone tried this?

Thanks all!
Steve
