Hello.
Im wondering whats the best MSD box to buy? Whats the difference?
Ive seen MSD 6, 6A, 6AL, 6T and so on. Im thinkin bout getting me an MSD dist and a box, but not sure. Does the boost retard systems take the place of a MSD box or is it something that hooks up to the MSD box and works off it to?
I found a ton of em on Ebay and found one that has a box, dist, coil for around 200 bucks. Is that good? HG

Hey gremmie,

The boost retard will work with any of the boxes. The 6 I would not recommend. The 6A is good, but does not have the rev limiter of the 6AL. The 6T I would have to look up. If you are doing boost retard on the blown chevy the 6BTM has the boost retard built in along with a rev limiter so you only have one controller. The $200 is a good deal if it all goes together and works. Probably over 500 in parts.

I know it isn't particularly sexy, but I use the MSD5 box. Cost is half that of the MSD6 and still gives you 6000rpm capabilities and all the good starting, idling, cruising, and accelerating features of the bigger boxes. If you will not be revving over 6000rpm, the '5 box is a great bargain.

I use a MSD6BTM on a blown 454 with exellent results the ignition retard function is superb for use on street motors and the rev limiter esential, I have used this on a stock 302 and c4 with the boost retard set at 0 and found it to work perfectly with slightly improved gas miage however I did blow off the centre pin of the dissy cap once, not sure if this was due to improved spark performance or faulty cap but never had any other problems, a good friend also runs a 65 mustang with a 5.0L HO in it and swears blind his MSD6AL is esential for reliable ignition performance. over here a MSD 6BTM costs £400+ that is $600, still worht every penny.
