I want to get a multispark ignition for my daughter's street car that she races. I want a built in rev limiter, and do not want MSD.

Looking at the Summit ($150), Mallory 6AL2 ($270) or????

What are your experiences or recommendations?

67 Coronet 500 9.610 @ 139.20 mph
67 Coronet 500 (street car) 14.82 @ 94 mph
69 GTX (clone) - build in progress......
