I came across this deal when I was searching through the Crane Cams website. They're having a closeout special on their Digital Multi Spark Ignition Box. In case you're not familiar with it, it's the one that Chevy Hi Performance used in their 305 buildup a couple of months ago. At that time they paid $130 for it, but now it's only $80. Here are the links. . .

Now I think it's only good for up to 9.5:1 compression, but you can call to see if it will still work for higher compression motors. He also said that it would be better to run a .045 gapped spark plug with this. Of course if you're running NO2, you'll need to use a colder plug. Like yall didn't know.

does anybody have any experience with this box, ease of installation, performance gains, etc..

 

Well, it should be just like your standard MSD box, 6A I think. As far as HP gain I can't be certain as of right now, but I will run this thing on the dyno and see. Even if it doesn't, my previous experience with these type of boxes, is that I get much better startup capabilities and improved throttle response. These things should be a requirement for carbs that live in the cold.

Oh, and thanks for replying. I was startin' to think that noone cared. . . 45 views and no replies.

ONLY 7 MORE DAYS UNTIL I GET TO GO HOME!!! I'm not counting though.

 

I installed a MSD system on my old 3.4 project.
(Yeah you heard me, 200rwhp from a N/A 3.4L)
We gained significant throttle response and a smoother idle.

I can't say how much power we gained, but I know
installed right VS installed wrong was a 20hp difference LOL!

 

Unless I searched it wrong, the part number for the SB V-8 is 6000-6300, which sells for $175. Although, apparently, you do get the coil for free, so its still less than the MSD.

 

Yeah, I think your research is right, but when I talked to the guy, he said it was because they're not making them anymore. All of their new stuff is "direct plug in."
