Wondered if anyone can help.

Have 1991 FXR 1340 Evo with Edelbrock Heads, HS42 carb with 4 inch velocity stack- open. Have fireball cam 316-2B. Accel programmable ignition 20 discs and open end cap. Currently have supertrap 2 in one. Is this adequate or is there better?

With the open end cap, you don't need 20 discs, the open cap is equivelent to about 8-9 discs. you could reduce the number of discs by that many and try it. Remember to use liberal amounts of anti seize on the screw threads.
