Msd 6AL ignition box

Summit RacingSummit Racing Verified Purchase

My first time using an ignition box. Was surprised at how much better the unit made starting, also makes motor smoother, more responsive, and burns fuel better. Wow, I'm impressed. Instructions to ignition box are simple. Easy to install. Quality is great, but most of all, it works. Glad I made this purchase.

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.

Easy install

Wiring and installation was straight forward. Purchased box to smooth out idle and for the rev limiter. Set it at 3,000RPM as a test to make sure it worked and could hear it kick in right at 3,000 on my tach. The dual dials make it easy to adjust in 1,000 and 100 RPM increments. Would recommend.

Some Disappointment

I purchased the 6AL, the pro billet distributor, the coil and wires, so I had the whole "she-bang" installed. System works well in my 74 Roadrunner... she now starts right up and gives me a much better idle. The only detraction from the whole system was that it wasn't compatible with my tach. So..after spending a whack of money on the ignition system, I now have to drop another $65 on the tach adapter. I would have thought MSD would have rectified that problem without requiring me to spend yet more cash in order to make the entire system operate as it should. Overall, a good product and I would recommend it, but beware of the "surprise" costs that may come up. ...read more

Summit RacingSummit Racing Verified Purchase

Installation is simple wiring diagram easy to read and understand. Love the simple adjustable rev-limiter function and the unit initializing feature to show the set rev-limit. My first digital capacitive discharge ignition module and I can't say I have had any problems with this unit. Nice compact size with simple disconnect harness.
