Nice compact coil.
I have been reading on the BIM- unit. It appears to have excellent dwell and amperage management which should allow for smooth hot high rpm spark. I am wondering if the LX- unit behaves the same or if it is more crude with regards to dwell and amperage mgt, like the original GM HEI modules. I look at the accel and msd HEI "performance" units and they claim to manage dwell better but they are freaking expensive.
