How To Distributor Tuning 101 Episode 409 Autorestomod

I've spent nearly the last 2-3 weeks searching for videos to explain timing to me after I put in an electronic ignition in my 67 with a 352. This is the only one to actually explain every step and make it comprehensible.

I timed my 69 f100 with a 390 from this video and had the same problem you guys did. 5 1/2 turns out on the vacuum can and no more knock and pulls hard. Thank you for actual info.

Wow! I came here clueless about vacuum advance and left with a greater understanding of how it functions and its purpose. Thank you guys.

Keep up the good work it's very encouraging to those of us who have Fords! I have a 67 F100 short bed I have to have it ready for my daughter's wedding next summer.

Tried to tune my son's 65 today and would run without vacuum line hooked up, wouldn't even fire above idle with it attached. Vacuum advance screw was screwed in all the way. Backed it out 6.5 turns and runs now. Figured it out because of this video. Thanks a bunch!

Man, I have been having a similar problem on my '72 360. I'm pretty close to doing a full rebuild to fix it. Can't wait to get back home to test this solution!

Very interesting, Jeff, this was a good one. I appreciate all that you guys have done over the years as they're some of the best automotive videos on YouTube. I believe that you're the guy that coined the term, "Restomod" aren't you?

I can really appreciate how much you're doing! If you haven't figured it out by now... You NEED to find a Ported Vacuum Port. It won't be in the usual places - especially on a 4100!! One of the Ports on the Pass Side must be Ported... 😉

Thanks guys I'm going to try that with my 59 Thunderbird. The engine is a 352 special but I think everything that you did I will be able to do on mine. My situation is that it fall flat off from idle so it seems like I have to give it a little squirt of the throttle and then it'll start go.

This is the first information I've seen on adjusting mechanical vacuum advance I can't wait to check my 71 400

Just started importing v8 trucks from USA to UK. Great video as we are picking up a lot of knowledge. We have just upgraded a 302 f100 to a max efi 500 system with electronic fuel pump, fans etc so we will be dialing in the timing tomorrow all being well that i can get the engine to fire once i set my rotary correct.

Helpful to see the process. At 10:59 you mention that your mechanical advance is about 32 to 34 degrees. Did you mean to say that the "total advance" was 32 to 34 degrees? If so, "mechanical advance" would be "20 degrees to 22 degrees (34 minus 12 initial=22 degrees). Really nice engine set up.

Another great video and all the best to you and yours Sir !!

one of you best shows here

And yes always set base timing because that is added 2 centrifugal timing for your total.

Great video. I knew it all except the adjustment on the distributor can adjustment via Allen wrench at 3000 rpm.

Ran across your video and I think I have the same problem. My vacuum advance is ported off the carb from the factory. I bought a 1973 Mach 1 Mustang with the 351C 2V engine. It runs like crap at 2500-3000 rpm, to the point where it wants to shut off! I can plug the vacuum advance line and it runs a lot better. A difference I see is my vacuum advance doesn't come on until I crack the throttle. One thing I haven't checked is to see if my timing strip on my NEW harmonic balancer is correct. Going to go through your steps, thinking it should help my problem. I'm still not sure about switching to manifold vacuum but I may try it. Thanks!

@ 7: 28 usually a port on the carburetor is ported vacuum , above the throttle plate . Any hook up below the throttle plate is manifold vacuum . I think I understood you to say your using ported hook up to the distributor advance .

Thanks for this! Very informative, as usual. 👍

I had an idea of what I had to do with my 79 T-Bird but this video was a great help! Unfortunately my AC bracket prevents me from putting an Allen wrench into the can... So Imma have a fun weekend this new years haha
