Brian, thanks for the phone call and explanation of the MSD distributor. With Christmas and ongoing projects with my new home I'm afraid a new distributor is going to have to take a back burner for now. If you still have it when Spring/Summer rolls around, I'd like to hear back from you. It was good talkin' to ya! Take good care and have a Happy New Year! - Brian

Your knowledge level is about the same as mine. I know something is happening under there...just not quite sure what. But if it is running "good every time" why take a chance?

BTW; Could not post when you put on the video...awesome job...thanks for putting me in it.

only ting that could prevent swapping the gears is if the old dist shaft is larger than the new one. Odds are it's the other way around and you might have to drill out the old gear to work.

you should be able to remove the rotor and mic the shaft to find out what the diameter of it is and then compare it to MSD's specs and go from there.

don't know Tim might be able to, just looked on summit's site and it does list chevy dist. as be applicable to both small and big blocks but they also list a clockwise and counterclockwise models for the mallory units so i would say it makes a difference.

they are the same SBC and BBC but direction is key for the gears to work.

Tim, would it work in my 305? Not sure I need to change tho. I constantly had ignition issues with the supra, especially in the spring each year trying to get it going. I gotta say the chevy always starts very positivley, even first crack in the spring. I'll probably just leave it alone, but I do hear good things about EI, so I thought I'd ask. What do you think?

Brian, I'd say you had a problem with the original distributor or ignition system. A gain in spark is not going to make a "night and day" difference.

...and the few vintage Nautiques that do have SBC's will be reverse rotation. Im assuming this MSD is standard. No idea of a modern EFI engine could use it, though those engines would be LH.
