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

beside the coil mounting discussion... if tried to use and tune a LD340 on a 273 with ported 318 heads... result: not what i would call a good set up, wasted a lot of time to get the carb in a proper running condition. and lost a lot of power at the bottom end.

as long as you not going to rev the 273 up to the sky... a LD340 will make no sense.

personally, i will make a switch to an stock 340 4bbl intake an add a TQ

btw... i´ve mounted coil and ECU right under the dash to get it away from heat
