E58 400 plus HP Dart sport build

Also updated the ignition controller I went with the orange Mopar 6800 rpm unit. Later if choose I will update it pro comp or an MSD ignition.

Should do fine with that ignition. My cam punks out at about 5500 and I have the rev limiter set to 5k for street driving.

You might wanna have your local transmission shop spec in a new converter for ya with that setup... likely need a bit more stall than stock with that cam.
