Holley sniper install

The Holley dual sync dist. (If that is what you're talking about) is setup and ready to go for timing control on the sniper. You can use a MSD dist, lock it out and buy a phaseable rotor and accomplish the same thing. It just takes more setup and can be confusing at first.

I'm not sure what ones your looking at but they shouldn't be $400 difference in price. The MSD one you'd want is this. MSD Ignition 8534: Pro-Billet Distributor Small Block Chrysler 273-360 | JEGS

The Holley is this: Holley EFI 565-208 Holley EFI Dual Sync Chrysler SB Distributor

I have a FItech and it's been flawless so far. However, the car was completely rewired with an EZ wire kit, in tank pump, new fuel lines and two 10 micron fuel filters. That all makes a big difference.
