Watch for differences when replacing old 6A

Summit RacingSummit Racing Verified Purchase

Aloha All, Replaced an old 6A (failed power lead as it would turn out, fixed and it is still working!). Not a drop in effort. 1. The case size different - Same length, however, it is wider (1/2" or so) this means having to drill out new holes and in my case move washer fluid bottle. 2. The leads now all go to one side (the bottom for me). This again, meant changing leads as they did not reach the new location as thy did before. Oh well, this is hot rodding! Mahalo, Michael ...read more

Smoother idle, more power and better emissions. I have no complaints and easily passing CA smog is just a plus.

REPLACED

Summit RacingSummit Racing Verified Purchase

THIS ITEM PLACED AN OLD "6AL" BOX, THAT WAS NOT WORKING CORRECTLY. I LIKE THIS ONE BETTER; BEING DIGITAL, AND THE REV LIMITER BEING A DIAL, INSTEAD OF THE THE CHIP.

MSD Digital Ignition 6AL

Summit RacingSummit Racing Verified Purchase

I have a 68 Chevelle SS with a BB 468. I was having problems with cold starts and idle. The digital 6AL seemed to cure the problem. Now my car starts right up and idles significantly better. The install was fairly easy, only took me about 1 hour. I am very pleased.

Insane ignition spark/power

Summit RacingSummit Racing Verified Purchase

The MSD 6AL is a must have for improved ignition, trust me, I know. This box is fantastic improvement for a more efficient ignition, it kicks out enough power it melted my stock coil pack, and I got unfortunately shocked a couple times by it while adjusting timing on the distributor, a bit of a kick would be an understatement. It is a bit time consuming to wire it in, but well worth the patience and results. Works fantastic with the MSD Atomic EFI system. ...read more
