Ignition boxes???which is best??

summit has came out with ignition boxes of there own,and i was wondering if anybody has used one yet,and if so,how well does it work???I havent never used an ignition box but i would like too..Im running a tunnelram and after tunning it for ever it seems, it still runs alittle rich,and i was told an ignition box would give me more spark ,and help to burn more gas in each cylinder...the one im looking at is sum-850602 summit brand

Iīve had an MSD6A box for a long time but recently I went from an HEI magnetic trigger to an MSD distributor and coil, MSD-8361 distributor ,
MSD-8207 coil .
Itīs a great setup and has done wonders for my idle.

I have got one of the Summit boxes as well, itīs still boxed so I canīt help you on that yet.
I bought it for some reason now forgotten so while the MSD performs well Iīll keep it in reserve.

Tunnel ram, eeewwww. They're fine for beating the hell out of, but I've never seen one set up that was as good as a single four on a single plane. JMO

I like the Summit dress up alum parts they are nice stuff and most plane no logos. As to ignition well you want good consistent fire for that fuel. I run MSD, but I am going to run Crane on the truck, no real reason for switching just want to try another quality ignition system.

With electronics you are paying for the type, size and spec. correct components. You will get what you pay for in this area even if you can not see the difference

Just food for though.

My friend had and msd 6a and it started making a real bad buzzing sound. He switched to the summit box and its been running good for about 4 months now. The summit box is just a rename of the mallory box.

the specs for each box is different and you do get what you pay for. Theyre probably all equally good if the models you compare have the same outputs.

I've had an msd6a box and timing computer for about 17 years I think with winter freezing temps and summer heat and no known complaints.

hey malc

Hi, Malc,

Just wondering why an MSD distributor would idle better than a MSD crank trigger. What was the problem?

thnx, jack vines

Never had a crank trigger, I had installed the MSD trigger in the HEI taking out the original module etc.
The MSD distributor and separate coil work better for me.

I have a Crane Hi 6 box....the short version of the story is after a small under hood fire the wires to the box were a little fried. Shipped it back to Crane with a note saying if you can fix it I will pay. They sent me a NEW box no charge with a Thank You for using out product letter... it was well past any warranty date and I had Visa in hand to pay for the damage....they even paid for the shipping! If customer service is worth something to ya buy the Crane box......Lorne

I just got the Summit street strip box with the rev limiter to replace a toasted MSD ( would not warantee). I spent an hour on the phone with a great tech at Summit sorting out a no spark issue. It boiled down to a bad coil (another fine MSD product). Bottom line the new box works just fine and throws a spark from h**l. haha

Funny this is the box bolted right in, including the wires. It even came with the long extension for the MSD dist.

Great item.
