I'm thinking of buying a multi-spark ignition box to go with my mallory dizzy? Is there any extra power to be had by using one of these?

 

Not much. The stock ignition is pretty good until forced induction is used. I have seen dynos showing nothing to around 5HP on mostly stock motors. Since you have a 10.7:1 motor it might help some. If you get one go with MSD. Iv had mine on for 8 or so years with no problems out of it.

 

MAN YOU WILL BE SURPISED ,,,BEFORE MY BOX IT WAS SLUGGAGE..AFTER THE BOX MSD IT WAS CRISP AS A HEAD OF LETTCE

 

not sure on the hp but you will defenitely notice a change. the idle gets smoother and throttle response is greatly improved

 

what box would you suggest for a stock block with bored and P&P e7 heads with a edelbrock cam and bbk headers and a 600cfm holley and MSD wires, blaster 2 coil, and the pro bullit dist. on my 84

 

I recommend the 6AL to anybody

 

I agree the 6al is a great box, easy to install, has a built in rev limiter and can be used with many of MSD's other ignition componants such as a two step or timing retard.

 

Yup, I went with the 6AL as well.
You'll notice a VERY improved throttle response.
And, it's rev limiter is much better than stock.
Cutting Fuel is never good.

 

i have the 6al, money well spent

 

do you notice any more accelleration when you instal it at all?
