Questions & Answers Ask a Product Question
Q:

Is there anything else I need to install this or is there anything else I should order that would work well with it?

Asked by JACK on August 16, 2017

A:

Thank you for your question. For most street installations, the 6425 will work with your existing distributor so additional parts are not a hard requirement. Many customers choose to also upgrade their coil to a matching MSD unit. If you choose to do so, take a look at the Blaster 2 coil, part number MSD-8202.

Answer This Question

Q:

I replaced the original delco distributor with an MSD 8528 and the coil with a MSD Blaster 2. If I will install a MSD 6AL may I get any improvement, more reliability or what? The car is a 1971 Firebird 350. Is it suggested in this configuration? Thank you in advance.
