well im probally going to get falmed for this because its not for my third gen but its still bowtie related... i have a 70 nova SS with a well built 427 with like 14:1 compression and all tat other stuff, im not going to bore you with details, so hweres my ?.. i have an Accel coil but no ignition box and i was looking into a box, mostly for the rev limiter... i really dont feel like over-revving this motor that i just got done building... it was a little pricy and i have a TON of time in to... so what do you guys like or have both good and bad experiences with? heres 3 i can think of off the top of my head

1) MSD 6AL
2) Crane HI-6
3) Accel 300+
