I was told that to lockout my MSD big block distributor I need to buy a lockout kit. Does anyone have the part number for this? I can't find it anywhere. Or is a kit not needed?

Not needed on mine. Drive the roll pin out. Pick the plate up, turn 180*'s (I think) and drop th pin in the hole. Drive the roll pin back in and it's locked.

Pretty easy to do... I locked mine out and have a stage 3 retard system...

Thanks guys, I recognize that diagram so I think I asked this same question awhile back. I'll get it locked out this weekend.

Bob if it's set up right it wont make any difference.

Quicktree, just having a timing issue, we're gonna see if this helps.

Well that sucks about the pin breaking.

bob i have the stops in there and locked out timing... its solid!

You may want to phase the distributor to prevent ring gear damage after the lock out especially using a start retard

Where did the diagram go? I don't see it on this thread anymore.

I have the MSD Pro Billet distributor part #8545. I removed the small pin at the bottom of the distributor and pulled the shaft out of the main body. But it seems like this distributor looks different inside than that diagram.

Here's a pic, click on it to enlarge....................

just go to medignition.com and look it up. you can print it.

Take the rotor off and you will see it as in the diagram.

Well, I got it apart and it's already been welded up, so I didn't need to do any of this tonite. I put it all back together and I'll reset my timing tomorrow. Now I'm really confused as to why I'm having this small timing issue. I have to set the timing at 39 at idle, to get 35 total when revving or just bringing the RPM's up. It didn't use to be like this so I'm not sure what changed. Cam shouldn't be moving forward with the cam button and timing cover brace.

Could the chain be streached?

bob I just unhooked my stage 3 retard system and it had 4* to it.... one guy noted thats how its setup,, yiou have the 7AL 3 right? see below

Note: The MSD 7AL-3 will retard the ignition timing approximately 4° compared to other MSD Ignitions. After installation, the timing should always be checked and adjusted at idle and total timing.

Timing chain was checked, it's fine but that was a good idea.

Thanks Sledge, I do remember someone mentioning the 4 degree deal but I guess I just couldn't make myself believe it since I've never ever seen that before.
That's actually not a good setup to have on the street since the timing has to be at 39 at idle.
But I did install the retard module selector this week so I'm good to go, I can flick the toggle switch and drive around at 30 total.

Bob, sell the MSD and switch to ours.. Many problems will be solved... Could probably sell the unit for the same cost of one of ours.. You know I love you guys...
