Holley Sniper with in tank pump no timing control as yet msd 6 AL box letting it learn first. Have only had it on for about 3 weeks has been running really well have put on 460 km so far and every time I drive it it keeps getting better. I've read the Holley forums and the bulk of issues are with setting up people jumping from carburettor to these and not quite understanding . Really important to read instructions a few times to get a grasp and run distributor and coil wires away from everything else due to RF issues. Run decent leads !
