ArdWrknTrk Posted November 29, 2019 Share Posted November 29, 2019 Dave - I think the Allen wrench you want to try is 1/8" not 3/32". However, I'm not sure that is accurate information because it comes from guys who are known to say things that aren't very accurate. It is from this thread on FTE. Seriously, I did a search for "crane adjustable vacuum advance ford 300 six" and the very first result was a thread on FTE. And when I started reading the text of the first post, before I even clicked on the search results, I thought "That sounds familiar." Indeed it was/is. Do they really make a special can for the 300? I thought they fit any DSII distributor. The only thing different ***up top** is the reluctor and the cap, right? Link to comment Share on other sites More sharing options...

And when I started reading the text of the first post, before I even clicked on the search results, I thought "That sounds familiar." Indeed it was/is. I will go out with my Allen set so I don't have to keep heading to the tool box LOL I did a Summit & Jeg's search: Jeg's did not list anything for the F150 truck for any motor? Maybe why I don't use them? Summit did list the Crane but think was for the 302 and was not sure it would fit the 300 six? And at $45+ I would have to do more checking before I pulled the trigger for it. Fingers crossed mine is adjustable. The others listed on Summit were Standard products non-adjustable, 6 different part numbers but no listing of the working HG so I don't know how you would pick the right one ? I did not think of checking over there to see if anything was listed. Didn't you post that at your show you did a vacuum adjustment and if so was this on a 300? If also so was it the stock factory can bolted to the dist.? Good news the Blue Top box has been ordered. Banker said I needed it so before she changed her mind I got it. I also checked both boxes I have and both have casting marks from Ford so core(s) should be good. Dave ---- Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted November 30, 2019 Share Posted November 30, 2019 Do they really make a special can for the 300? I thought they fit any DSII distributor. The only thing different ***up top** is the reluctor and the cap, right? Well, I guess Gary schooled me. I definitely did not remember that thread.

Read a bit more in that thread and those yokels suggested that the screws may come in from the bottom. Dave - Glad you got the BlueTop on order.

Gary Lewis Posted November 30, 2019 Share Posted November 30, 2019 Well, I guess Gary schooled me. I definitely did not remember that thread. Nor did I! Looked at the search results and thought "That's kinda the way I string words together." Then got in there and it was deja vu all over again.

Looked at the search results and thought "That's kinda the way I string words together." Then got in there and it was deja vu all over again. I went over the link you posted on FTE and if I understand it the factory cans / vacuum advance units for the 300 six could be adjustable for 81 & 83 and not sure on the 82? I will check and hope my can is adjustable as we (me) are not sure if the Crane unit will work or not. Also when I looked up the cans on Summit Racing, Standard products, none were adjustable from the details. So unless mine is not adjustable I will need to find a Motorcraft one for 81-83 300 six. There is hope yet Thanks Dave ---- Link to comment Share on other sites More sharing options...
Rembrant Posted November 30, 2019 Share Posted November 30, 2019 Do they really make a special can for the 300? I thought they fit any DSII distributor. The only thing different ***up top** is the reluctor and the cap, right? They appear to be quite a bit different. The small block 302 and 351 distributor has the vacuum advance arm inside the housing like below: The 300 has the cannister and arm outside of the base assembly... Going by those pictures, the vacuum advance mechanism is similar, but not the same. I crudely put the 300 distributor beside the Crane advance below, and at a glance, it doesn't look like it would work to me, but I could easily be 100% wrong. I'm just screwin' around. Dave, I *may* have a Crane vacuum advance you can use, I'm not sure yet. I have a new distributor coming from Parkland Performance soon, and he will be sending my old distributor back (and it had a Crane vacuum advance on it). Only thing is, I'm not sure if he was going to reuse the Crane advance or not. I probably won't have it back for a couple weeks, so I don't know.

PS: Also, if you look at the small block vacuum advance and the Crane unit, there is a bend in the arm, and the 300 vacuum advance arm appears to be flat.

Good sleuthing Cory, and I appreciate the side by side comparison. Gary's link to the FTE thread kind of shows the how and why but you (and the I-6 fan base here) certainly have a better handle than I even remember having. Maybe Dave's dizzy already has adjustable advance. Maybe someone has one to offer up in the marketpace/FTAGH. Maybe another answer is to put a hard stop to the amount of advance the vacuum canister can pull in. Link to comment Share on other sites More sharing options...
Rembrant Posted November 30, 2019 Share Posted November 30, 2019 Good sleuthing Cory, and I appreciate the side by side comparison. I don't know anything...lol. I was just screwing around on RockAuto while I'm sipping my first coffee. I have the Crane kit on my old distributor, but I don't have much experience with the 300/6 stuff. I am oddly fascinated by the 300/6 and would love to have a Bullnose with one...maybe someday! But, we do have some 300 Experts on here, so I'm confident the boys will sort out any issue in short order. Link to comment Share on other sites More sharing options...
