Hello everyone. I have a 1984 CJ7 with a Newcomer Racing 4.7L stroker (mild cam, blended head). It put out roughly 311 HP & 321 TQ on the dyno with a carburetor. I currently have a Sniper EFI on it running a DUI/HEI distributor. I hope to learn more about the MSD and Holley Dual Sync distributors to see if I'm missing out, LOL.
