- Setting the timing on your engine is one of the most misunderstood adjustments, but the information on this video will help you understand and answer all of your questions about ignition timing.
This is seriously THE most informative video I've watched on youtube. I feel like I just sat through the most interesting course I've ever taken. THANK YOU for taking the time to teach us knuckle heads this stuff!!!!!!
Freiburger, you are the Bob Ross of small block Chevy's lol
After 65 years of thinking I'm the smartest guy in the room I find it impossible to perform even the most basic of functions unless I fully understand the reason why and I can't fully understand that reason unless it is presented in an interesting and succinct manner. These two young men are perfect... Gotta Love It... Thank You!
Yep, any schmuck can be told how to do something and they'll do it. Only he who learns why, will do it well.
I am a simple man, I see David Freiburger, I watch.
Cum Dumpster yep !
sweet, i just learned a months worth of knowledge in highschool with this 9 min video.
MSD just earned a new customer : ) thanks for the video.
omg, im diagnistics/ fuel class and you teach this alot better than my instructor
Well done ! So often the amateurs know their subject but not how- to on videography ... bad script, shaky camera,lighting, etc. But this is so easy to watch. Except for the music, which doesn't add anything. Thanks !
Absolutely fascinating. I will never take my mechanic for granted ever again. Thanks guys..
Thank you. Very much. For. Your. Addition s
Awesome mullet, Mr. Freiburger. I also appreciate your professorly explanations.
I think MSD products are great and your
video was very informative ..Thanks
Tom
I like how they say each car has different timing settings. Most other videos will just tell you how a timing light work and how to adjust the timing which is good but NOT all timing specs on all cars are the same. Simple straight forward video. Thanks. I'm getting a timing light soon.
Now if you don't understand what these 2 guys just explained. .. Give up.. Great explanation,
Thank you. Been reading and watching a lot of tutorials. Yours is the most informative.
Finally, a video about timing light I understand. ThanX
Very very useful and great info I just learned. I was having issues with my 305 timing. Now I know how to adjust it
Great video. I just learned a ton by watching this video.
Definitely subscribing very detailed, easy to understand, and your workin on Chevys, thanks for the great info guys!
thanks for taking your time explaining this its been a real big help to me big thumbs up mate
I don't care that this is all very old information for me. I watched because of David.
thats a bit gay dude
AWESOME VIDEO!! Very well explained!
FREIBURGER 😂😂😂
great to see a vintage Freiburger clip....and it's useful!
Ken Wright so true !
That one dude seems like he knows cars and is a good presenter. I think he should stick with this “Car Videos” thing.
Hi Guys, big shout from Germany. Hell of a good training lesson on how to tune up your engine. Thank you alot guys. Would be nice if you get over the pond and tune up my Dauntless 225 with me ;-) Thanx, thanx, thanx!
roadkill before roadkill
He looks so much younger!
Haha that mallet hair
yeah, back when he had hair...
DAC087 Mallet hair? Hair you put on with a hammer I guess.
I wonder how many other Roadkill related videos are floating around here.
What ever happened to removing the hood and having you mechanic sitting in the engine bay adjusting it for performance while you nail it down the neighborhood streets for the best results physically
tuning it? No Seat belts?
Eric Lubeck Been there, done that.
Eric Lubeck unfortunately my friend those days are gone. However it does bring back some great memories of hanging out with my buddies talking about how fast we could go and who had the fast car in town.
Eric, did this literally on a 1973 K5 Blazer back in California about 30 years ago...my friend lost some hair...FIRE!
@catburner Try 8 deg. btdc, which is what the 1988 305 ( in the C1500 ) timing spec is. Install distributor only after the damper slot is aligned with 8 deg. btdc (compression stroke # 1 cyl.) When installed, the dist. rotor should point exactly at the # 1 cap terminal. Then tighten down and test with timing light. Should not harm engine.
Good video guys. Looks like you have a very cool job.
Great video very well put together. thank you guys
Please respond to me.. This is in my opinion the best vid on you tube very detailed but you missed one thing. Vacuum advance. So with vacuum advanced disconnected and plugged i am at 11 BTDC. When i connect the vacuum back up im at 30ish BTDC is this the correct way or did i mess up.
Hook up your vacuum advance so it only sees vacuum when you crack open the throttle. Hooking it up to manifold vacuum (vacuum going to the dizzy when at idle) will give the engine a quicker, more peppy rev, but it's not correct and often causes detonation which isn't audible since the engine isn't under much load when at very low throttle angle.
Hey look! It's a younger Freiburger!
you're a good teacher!
@gmcjoshua follow the spark plug wires back to the distrbuter nd make sure its the right wire for the right cylinder. theres going to be a set of numbers on your block the shows you how the distrbuter is supposed to be wired. the front of your distributer might be 1 then . 8 being on the passenger side and 1 on driver side.
Just when I tought I knew something about engines...
David had an impressive Kentucky waterfall back in the day
Fantastic Explanation who is this David Freiburger guy, he should write for a car magazine or something like Hot Rod, jk, LOL
RoadKill!!
@TORIANO50 something might be pinched. check your shift linkage when you put it in reverse. either that or you might have a bad motor mount.
Excellent Videos..!!
Upload more please...!
hi, when you set your Total timing at 35deg 4000RPM do you need to UNPLUG the vacuum adv ??
and I got a MSD 6al ignition box, does it will affect the reading?
get a strobe light as the one in this vid, hook it up.
disconnect the vac line of your dizzy (and plug it temporarily with a screw)
start engine and let it idle (800-900rpm)
aim the stobe light at the bellhousing on the carb side of the engine.
if you see the 'steel ball' in the middle of the hole then your timing is OK.
If not, twist the dizzy back and fro until you do see it.
When done tighten the dizzy clamp bolt and re-attach the vac line.

I want freiburger working on any Chevy smallblock I ever own.
Freiburger rocking that curly mullet!
Very informative video but does people use those antique ignitions? I thought ECU controlled and computer adjustble stuff was the thing today...
Great job guys!
@MSDvideosdotcom blue smoke is oil, white smoke is antifreeze.
@catburner Static timing means "to install the distributor at the specified timing" as indicated on the emission sticker. When the timing pointer is at , say 12 deg. BTDC on the compression stroke, then install your distributor.
You don't install the distributor at 0 deg.
Excellent video, thanks!
Wow Dave before the roadkill days
@mariahkraft
Depends on the car. If the car is using a CC distrbuter (common on late mid 80's chevy that used CC Q-Jet's) Then the timing is computer controlled and pretty much hard programmed into the chip. The only "setting" that is done is simply unplugging the data cable on the distrbuter it setting it to true TDC at idle and plugging it back in. There is no real adjustment to them. Short of reprogramming the chip (its written in stright assmbley so good luck with that)
I know this video is quite old but the timing still doesn't make sense to me.
Do you set the cam physically to 12° BTC or do you leave the engine at 0° and rotate the distributor until the light reads 12°?
For a big cam BBC or SBC you need min 18 or higher initial timing with a MSD that would be the black bushing, use the one light (silver) and one medium (blue) spring.
Hey i kno the steering column your talking about, on those column even ones that go into the 90s have rod that goes from the center of the column under the steering wheel and down to the just above the brake pedal there is a little switch , if the bolts in the switch get loose which they always do it will kill the ignition power just the way the key would if you turn it, sometimes they are adjustable and need to be set with some trial and error to adjust when turning the key activates the switch
I used 87 on a premium only Acura 93 vigor.... Failed ignition timing (09 BTDC) during a smog check because of the gas I used during the test.. It would be great if you guys made a video explaining why this happens.
"cause Roadkill. that's why. Last engine I built was a 340. It didn't turn over half a turn and it was running. I don't need to watch this but I still do.
Most of us don't have your neat little white strip on our harmonic balancers showing the timing degree. Most of us just have a mark. Sooo, what are your thoughts on setting timing without your little cheat label?
Hi guys awesome video, I have a maybe a stupid question? Can I set the ignition curve timing, in my 1989 Toyota truck? It has a basic original engine, nothing fancy, thank you guys, cheers from ontario ca. Let me know please
Did you remove the vacuum advance hose from the distributor when adjusting the timing?
Were would you set the timing on a 1946 Cadillac Flathead V8. I marked TDC on my Harmonic Balancer, when I had the Head off. When putting the timing light should it fire before TDC or after.
My Harmonic markings were long gone. ANY HELP...
Thanks
Freiburger really had a mullet, I'm impressed.
what about EFI ignition table when using a turbocharger ? that will be great
koay i bought a 6al with pro billet and blue blaster and it worked sweet but recently i picked up a 307 impala with no carb or distributor so i looked on the net and ended up buying a streetfire ignition because it was guaranteed by you msd and it was cheap now ive fitted it double checked and triple checked the initial and played with the advance it tries to run but if i give it gas it backfires like an animal,also fitted with brand new holley do you guys get many returns of these
Dude u guys rock bro! Always intrested in watever is said by u guys!!!! Long live the muscle car & horsepower!
This is really interesting. I've known how to check and adjust my timing for a long time but never really knew why I was doing it.
Great vid. Keep it up!
grat vedio...thanks for information
so... was the vacuume advance hooked up or plugged I did'nt even see a thing on the distrbutor
I bought a used 383 and the guy said to set it to 26 btdc total timming with the vacuum plugged, then plug it back in and adjust curb idle. It sounds good at idle but cuts out at part throttle. I set it to 17btdc with vacuum unplugged then plugged it in for a 2btdc at idle. It runs good like this so.......what is going on? I know a 383 usually has a total timming of 30-34btdc, so what do you think is going on here?
great video
have you found out what was wrong? if not theres a number of things to check, clogged exhaust, lean condition/fuel delivery, broken harmonic balancer, alot could cause this problem
Freiburger wore that same hat when he watched X-Files I bet
This is interesting. My ready to run MSD came with he heavy spring and green stop bushing installed. Being a ready to run you qould think guys would mainly use it for mild engines. The way it comes it only allows about 16/17 degrees of advance at 3200 rpm. the car likes around 10 degrees at idle so i was only getting about 26 degrees total advance.
The SBC ready to run should come out of the box with blue springs and the silver stop bushing installed and I feel it would be way more "ready to run"
you guys have great teaching and explanation skills. Loved the video. Thanks for the knowledge too. Much appreciated and thanks for being generous with your knowledge.
Good information! However, this only applies to distributors without vacuum advance. For you guys with standard engines and distributors this is not the correct procedure. You have to get specs for your particular engine and check it to them. Note: Timing with vacuum advance connected could very well be about 30-45 crankshaft degrees advanced at about 2000 rpm.
Y'all forgot about vacuum advance. SBC's love direct vacuum advance. BBC's will miss fire at idle, they like ported vacuum advance. You have to play around the more change from stock you have. Even stock, the above holds true.
You guys should get with an audio engineer and show us what detonation sounds like when we advance the total timing too much... Just so we can know what's too much >.
it sounds like a ticking sound, then if you go too much it goes to a sound similar to dropping a brick on pavement.
hey i have small block 305 chevy , stock evrything , and when ever i try to adjust my spark timing , after i set my engine to tdc " 0 mark " @ idle i shut off my engine , connect my est plugg and start up again my engine advances itself 15 degrees and runs real rich " white smoke out of thetail pies" what am i doing wrong ?
also, this is a quick fuel mechanical secondary 650 double pumper on a 414 windsor motor.
I have to replace my timing chain on a 2000 Ford Taurus. Do you have a video for setting timing on a non distributor engine?
Hi guys! I need to time my 502/502 Chevy crate motor I bought about 14 years ago. Please tell me what settings and ranges I need. I'm sure I will convert over to MSD soon, but for now I have a regular HEI (I think) distributor. Thanks a bunch Norm
And yet this video isn't high performance, seeing as it was filmed with a Potato haha.
Do ya time with vacuum advance connected or leave off and cap the carbs port??
Again best video on youtube
How much ignition timing needs to be changed after installation of MSD 6a kit on GM chevy 350??
I thought "Haha, this dude looks like DF in the thumbnail, Imma check it out"
Well, I'll be damned. It is, indeed, a young DF.
Got my HEI from china for 45.00 new on e-bay for my chevy small block. Works as good as a MSD for about 1/6 the price.
Smoke out the tail pipes usually means its burning oil- Black smoke is usually a rich condition.
good job guys
Would advancing your timing make you idle at higher rpms and inevitably burn more fuel??
Is changing the timing belt likely to corrupt the engine timing? My car started having a lazy start as soon as I had the timing belt changed. should the mechanic have checked the timing as part of the belt replacement job?
It'd probably be a good idea to check the timing anytime you mess with the timing chain or distributor, I've learned that lesson the hard way lol. If either of the gears were moved out of sync with the belt off it might have thrown the pistons and valves off which could leave your cylinders vulnerable to get fuel/air into the cylinder during the exhaust stroke or not completely empty the exhaust out during the compression stroke, this could also cause premature detonation but if the timing is jacked up at the timing chain, turning the distributor isn't going to be the fix because the cam shaft and the crankshaft are still linked together at the timing chain. You'd need to disconnect the timing chain again, set the 1st piston at TDC then take the valve cover off and turn the cam shaft until its set up like it should be (taking the valve cover off lets you see the valve train and lifters so you can see if their set where their supposed to.) Then after your comfortable with where the cam is in relation to the crankshaft, hook the chain back up to the gears in the timing box, throw your valve cover back on unless you enjoy an oily mess everywhere then fire her up and see where your at.
What sort of "mechanic" did the timing belt job? Some engines are a breeze to do a timing belt on, like the 2.3L Ford and most other single cam engines aren't bad either. But if you've got a V6 or V8 with dual overhead cams, or even a straight 4 or 6 with two cams (not nearly as annoying as 4 cams), it's not a job for a lot of 'shadetree' mechanics. I highly suspect you have at least one cam that's a tooth off. Even a pretty good mechanic has that happen sometimes. When the timing belt tensioner is set, it will move the cams a little and if that's not compensated for when putting the belt on, it'll be a tooth off. That will surely cause sluggish power and usually not as quick to start.
@seapeddler done ! its too much advance , too much knoc for the 87 octane im running . did it have the c1500 have the samecam ? ,
Could you make a suggestion on the best distributor for a 76 cj7 jeep with 258 engine and a GM TBI fuel injection system? (The ecm has spark control but I will need to upgrade my distributor since I currently have a prestolite ignition system)
Thanks for another great video! :)
Nevermind... I got a duraspark dizzy... Now need to find a good coil for my newly tbi installed system...
Still... Wish I had a good/single man to help me on my peep.... :P
so how do i find the timing if i dont have that sticker on the balancer? its an old engine out of a 71 and it runs great but i can tell the timing is just a tad off bad listening to the engine run.
Dude its "fryberger" the blond dude is fryberger from the car show ROADKILL!!!! how cool!
Exactly.
From the show Roadkill, LOL, yes he does the that show but only for like 3 years, he is the man the beast behind Hot Rod Magazine for like 20 years
Looks like I'm not the only one watching just because of Freiburger lol
I've not seen the "total timing" spec for the cars I own. Do all cars have this spec, or do quite a few of them just have the timing spec. for Idle.
sounds like your timing is to advanced if it does not want to start back up and also would cause your car to sputter,kick and snort when you go to shut her down. I would start by taking a hair out of your timing until it starts nice again. You might also need more octane in your fuel that could also be a problem.
at what RPM do you set the timing on a small block chevy, you guys never show / tell us that, Chad just revs the carb up with his thumb and you say look at the timing advance as the RPMs increase, ok, well when the engine drops down to 12* what RPMs is it at
3500
How 12
+gReGsKi GmAiL rev until timing stops increasing, normally 3500-4000
3500-4000rpm.
Hi sir, can you give me one example answer for my question? Example for like n14 engine/Peugeot 1.6 thp with the undersquare, compression ratio like 10.5.1, turbocharger, direct injection, 6 speed auto, no marking degree, and result for that engine like computer scaning, as result -1 ignition degree, minimum degree like 15 to 18, maximum degree like 30 to 34 degree, so if you like mathly counter in your brain what - ignition degree would like you choose for that engine performance would be better?? Hope you can response and give your answer sir. 🥲.. thank you very much sir.
I need some help long story.We replaced motor on 2006 silverado with new crate large block 5.3 swapped everything new flywheel installed in truck but motor won't start just barley turned over it has no distributor all electronic & computer what do I do
