hi i have a challenger with a 440 engine with a292h comp cam and a torker 2 intake and a750 speed demon and im thinking of upgrading the ignition! now i have a mallory distributor with points mechanical advance i think!! and i dont remember the make of the coil i`ve got!
the car has run 12.2 on the quater mile!

im thinking of buying a
MSD-8546 mechanical advance distributor. found it on summit!

and i think i need a msd 6al ignition box with it!! can someone tell me
if this will fit my application is this a good ignition combo for my car????

pleas help me it is expensive stuff so i dont want to make an ass out of myself

That is the same distributor I was thinking of getting.

The thing to watch out for is the type of connection on the cap. This one has male HEI type connectors on the cap. So you need ignition wires to suit such as MSD-32739.

Any of the MSD ignition boxes will do. They have more features the further up the price range you go.

I personally will be going for the MSD-6520 Digital-6 Plus version because I want two rev limiters. One for the burnout (linked to the line-lock switch) and one for running up the track etc.

Don't forget you can also get "ready to run" distributors from MSD such as MSD-8387 that have everything built in. No need for a seperate ignition box and they are a direct replacement for the stock distributor.

ok thanks alot do you think the ready to run distributor is as good as the other with the box??

It is a million times better than a points type distributor that's for sure.

I have never even seen one of these "ready to run" types let alone tried one. So I have no idea how good they are. They certainly will not have all the features of the bigger systems. But do you need those other features?
