Rev-N-ator ignition boxes?

Take the 40hp claim with a grain of salt. Ain't no way it's going to make a 40hp increase in a 350hp engine from an orange box. Biggest issue with the orange box is it drops timing at higher rpms.

The rev is a good unit. If you want to stick with a factory looking box with extra features it's a good choice.

There's a big thread on moparts about the rev box.
