302?

go to lowes and get a laser that shoots the + dual lines and use that to check the 90 degrees, much better than a sharpie, on line on the valve stem, one line for the rocker

What about the valve seal?

Good looking car! How much boost?

I learned something today to back up my method !😊

What gear ratio?

Interesting

The proper method isn't primarily a "BULLSEYE" center stem pattern, but the minimum RA from/back ARC swing movement. That will translate to the most full transfer to linear vlv movement.

This is the best/ easiest to follow video on rocker arm geometry I have seen yet! Great explanation! Thanks for taking the time to make the video.

If you have no idea of the camshaft specs , how do you measure the lift? Do you measure the travel of the valve spring?

Looks right to me, i learned the same procedure many moons ago, it works every time,👍🏻💯

In my best Jim Carey voice from The Mask...SMOKIN' ❤❤❤❤❤

570 lift 285000 everyone knows where you determine those numbers from! Right

Fucking magnificent. This is my sign to boost my 331

Excellent method

I'm trying you're method but i have Howard's link bar lifters(ford 289) When you spin the motor to check 45 degrees angle at half lift my plunjer in the hydraulic lifter will collapse .also when checking valve tip mark. Doesn't it give you a false reading? Thanks

Sweet! 🦊💯🔥

I tried using this method, but in order to establish the 90 degree angle (with valve closed) and getting the mid lift, I need to have longer rocker studs. What am I doing wrong?

SIR WITH ALL DUE RESPECT IT'S NOT TRINYN ITS LIKE ONION TRUNYUN TRUYON LIKE ONION ALL THE BEST AND THANX FOR YOUR EXPLANATION ON ANGLES 👍👍😉

Thx

Thanks for that! I'm glad you showed how to do this without checker springs, and just using the actual valve springs. Well explained Sir.

Good video but you drew the wrong line on your rocker arm. The line of action is from the rocker pivot to the roller contact point, not the roller center. The valve only cares about what contacts it, the roller OD.

Who is the best engine builder in the world who taught you this just asking

Sadly due to BABVVO and TEBBVO laws soon all gas cars will be banned in EU and USA!

Dump that junk mic and get a none digital mic. That's the first thing.

Still need locator cups for steel heads?

The caps lock and exclamation point make me very excited about this

What a guy. Anotonio is really one of the GOATS. This guy really knows his stuff. Can't wait to see him racing F1 !!!🏎

I have a Chevy 01 cavalier 2.2. 134l that I have built for oval track and would like to put roller rockers on but have no idea what components to use I would have to tap the head for studs. I believe the ratio is 1.5 stock camshaft with hydraulic lifters. It has pedestal mount rockers now but the bolts are very light duty and I am running 6500# valve springs. Just rotating the motor broke one of the studs off. I believe they have to be self aligning rockers. I seen this motor with roller rockers so I know it can be done I just don't know what parts I need to accomplish what I want to do, any help would be greatly appreciated,thx

Just a turbo? or do you have heads and intake?

what size tire on those rear 18s

real man drive a tko 💪

What kind of hp did you put down

What do you do when you try this method and don't have enough threads sticking through the pivot shaft to even begin to thread on the nut?

Great Video, Thanks for taking the time to put this out there... not to much info on this topic. Huge Thanks from New Zealand.

You didn't mention if this was solid or hyd roller. Nor sis you subtract for the lash or have a light spring for hyd setups. Pooor t best.

Is rocker arm ratio the same as mechanical advantage? If no, how are they different?

How is it on the street?

Really a good explanation 🌹

When working with a hydraulic lifter is it still necessary to use a solid lifter for this method?

I have a set of older TFS twisted wedge heads on my Corvette. They require different rockers and pushrods for intake and exhaust. The sharpie marker method is exactly what I used to get it right. Good advice and great video explanation.

Do you have an ig

Can you please share how to time the cam shaft

Bro nice vid, love the powerfist dial indicator, I have the same one it must be a Canadian thing :)

very very important part of building that the average everyday person dont know about. thank you sir for this very detailed set up video.

Needing to find pushrod length for my build, the cam I installed has different lift for intake and exhaust so for proper geometry I should run different length pushrods?

you need to point out this procedure is at the base of the cam lobe, you also need to point out this includes the head gasket and head is torqued to spec.

That’s why I never use digital measuring tools.

Great video! Thank you very much for making it

I did mine with the mid lift method, but the roller is out on the exhaust side closer to the edge. It's a sbc with a hydraulic roller and + .100" valves. If I put the sweep in the center, the patern is about .125" wide. With it out about 3/4 of the way out, it's only around .050" wide. I haven't fired it up yet, but I'm thinking of putting lash caps on it just to be safe. Got any advice? Scorpion 1.5 rockers btw.
