One reason i use the MSD 6T box....it can be fixed. The last one cost 35.00 bucks. Just takes 4 weeks to get back.

No one mentioned the pro comp box. I've had on in my 19' for 4 years now. Not bad for the money.

thanks I got a new one from jim ried right away, thanks though. Artie done for the season well until march, might have to pull the motor to do some work.

Not to sounds like a complete idiot, but why run these boxes, aren't they overkill for most of these engines? I just run the stand alone distributor and cranked out close to 550 horse with it...

My case I always had issues with the Merc chips with the cams i run so I went to a pro comp dist and box. Picked up 200 rpms and made idle perfect. On the race boat I found 2 MSD 6 T boxes on eBay for less then a 100 each. Just cheaper buying the Merc's.
