- It's not always easy identifying camshafts. Very often their ID numbers are stamped sloppily, or too lightly, or in the case of this vintage Chrysler Direct Connection cam, sometimes there are no numbers at all.
Here's a way that you can ascertain one simple measurement from your camshaft, and with a little detective work, find all of the other specifications for it from published catalogue listings online.

The first time.... everyone who started on their own with a manual and no mentor forgets how long that first time took. The first time I popped out a valve must have taken me half a day because I was nervous about breaking something. Same with installing break springs. Do it a half dozen times, learn a couple little tricks, get it done in no time at all, and you feel like a god.
In what universe does a brand new dad have three minutes to himself?
Everyone always thinks a job will take 10 minutes. There's always unforseen things that happen or come up that makes it take much much longer.
I’m with you Russell Mooney. I’ll go further to say the person that can do it so fast stuffed with hot dogs probably spends the time savings pulling the transmission fixing the crap they twisted off and broke being hasty. So great job Josh!!
Josh is a Trooper, lota ppl EAT hotdogs better than they DO anything else .
In the 80s I had a flat cam on a 318 aspen went to the machine shop they gave me a cam worked perfect no break in no special oil and minimal skill and knowledge on my part car ran great after that . Now I’m more confused the more I have learned 30 years later
Back when dinosaurs roamed the earth, before the internet, things I was able to dig up on the LA engines, specifically the 318, I found the recommendations for the Mopar "purple shaft". But I was led to believe that was only one cam. But nooooo. There were several. There was also the .474" lift and .484" lift cams, which were also "purple shafts", and the one I wanted, I found out, was the .450" lift, 268* purple shaft. The internet sure makes things so much easier these days. Something else I discovered, cam lift vs. displacement. The same cam in a 318 gave far different performance from using it in a 340. The 273 "Commando"/"Charger" engines had a hot cam, you'd have thought it was huge, but only .425" lift or so. Comparable cam in a 340 would probably be the .474" lift cam to that little 273's cam. I'd be interested in a good discussion of lift vs. displacement.
We used to call it a Hemi grind. I got them wholesale for $36
Hang in there, Josh. Don’t pay attention to those critics.
"I could of done that job in 18 minutes with a mouth full of hot dogs."Good fer you!🤣🤣🤣🤣
Anyone who belittles a beginner, is an ass. You, "uncle tony's garage" and I, share the desire to pay forward our accumulated knowledge to the lesser learned. It astounds me how many want to say crap to the starter's. We, ALL OF US knew nothing at one point. Thank you "Uncle tony's garage"!!! Edit (I don't have NEAR the experience that you do with serious 1/4 mile drag cars, nitromethane, ect. But rather a very long list of budget builds on small and big block Chevys. That continues to this day. So many are hell bent on "everything perfect, factory specifications" type of building. Not everyone can afford this. One can have a lot of fun, gain a great amount of knowledge, by just doing the best you can, with a very measly Budget. Patience is the main key. Thanks again UTG, you are one of the few!!!)
I still can’t believe that I got to shake hands with the legend that shares all this amazing information with us :)
Send Josh my congratulations, at least for getting this far. Thinking about doing it is a lot easier than turning wrenches and actually doing it.
It's great you are helping to preserve our hobby showing people how to work on there hot rod .
I had a guy give me a purple shaft cam years ago and he didn't know anything about it so with this info now I'll be able to. Thank you for putting out the info
Well done video! Thank you so much. I recently inherited a late 60's SBC and was hunting how to identify the camshaft. This makes it easy to know what I have. PERFECT level of technical speak; not over our heads but also assuming that we know the basics. You know your audience!
Its guys like him that want to learn it without excuses that make you want to pass it on.
Bloody good uncle tony…!!!!
You answered my question at the end about the hydraulic lifter not being as "stiff" as the solid, used to have to adjust my solid lifter cam, a GM phase 2 that was a 512 lift at .28 intake and .30 exhaust, if I remember correctly. Again good content and infro uncle Tony.
Well hell! The next time I Need this job done I'll call ol' 18 minute hot dog boy and then I'll stand there with a stopwatch!
