Holley Sniper hyperspark Ignition System

Postby posulli88 » Tue Jul 10, 2018 9:09 am

I am getting ready to add in the timing control feature on my Holley Sniper. I have an MSD Ignition System (ready to run). I have read that a lot of people have had some issues with the Sniper system controlling MSD Distributors. Through that research I ran into this system:


I think its very new, but seems like a solution for amc engines and timing control. Wish this was out 4 months ago when I bought my MSD system :banghead:

Anybody used this? Thoughts? Anybody here have success with timing control with MSD?

I have it with my fitech.

You have to lock the distributor, phase the distributor, then sync the physical timing mark with the handheld timing at 2000rpm.

Mine is set at 16.5 at 2000rpm
