Well said Tim, maybe you decided this was not the vid for it cause the reasons you mentioned are spot on, but for those that really don't want to listen or think your wrong. One other reason for flat tappets not working on a roller is the ramp on an even milder roller cam is so aggressive that corner I'll say, will cut into the lobe of the cam. Good stuff, it will help 👍

Great informational video, Tim!

The only thing I saw you missed for cam& lifters, please always remember to clean the lifter galley the lifter must move free it may or may not wipe out a cam but it'll sound like a rod knock. Ask me how I know. Great job👍👍🇺🇸🇺🇸

Solid lifter cams have a slightly different "ramp" than a hydraulic due to the difference in the way lash is taken up during operation.

Telling it like it is Tim. Sadly, we may all be running Rollers before it is over. And I still like flat tappets. Thanks for sharing. Take care, Ed.

thanks for the Tips Tim. tips from Tim, I like it

Great profile analysis, keep up the good content.

Great video and great explanation Tim!

Thanks for explaining that. Didn’t know that info. Last year when I built my 360 I put in a Hydraulic roller cam $$$ because several freinds were loosing motors with solid lifters. 👍

Very well explained. Thanks

That was a great explanation Tim!

Love your videos, good education

Thank you for the info Tim.

Great video!👍

excellent explanation!

Well done!

Great stuff!

Great tech !!

Good info!

Nice comparison

Thanks man

Good information 🤙🤙

You briefly mentioned my one 🔥 BURNING 🔥 question. Why, does a roller cam cost two to three times as much as a flat tappet cam? I mean, i cannot see it taking two to three times the labour or material to produce one! Grrr! To the cam manufacturers.

Also worth mentioning that flat tappet lobes aren’t centered directly under the camshaft either. That’s to assist with lifter rotation. This is why you can’t use a flat tappet core for a hydraulic roller regrind. Only a little over the roller will be in direct contact with the cam lobe.

Just one of a few things people cant cheap out on

👍🏻👏🏻👍🏻

Tell me something you may know about the after market roller cams for the late LA and Magnum engines. If I install the cam from say Comp will I have to run a bronze gear on my distributor like you had to do in the old days? I know a lot of factor roller cams have a cast iran gear pressed on but I don't know about the after market replacement cams. Thanks, DC

👍💪

Is general engine breaking oil is the same as your camshaft breaking oil?

Oh man. I have a jar of mopar perf cam lubricant allso. Warnings on the cover are impressive like,,. If opened outdoors, polar bears and pandas in china will die instantly. If you even look at the stuff without a gas mask,, you and your whole family will die,,probably your neighbors too ETC. In the end there is a text, Theres no substitute for quality 😁 Must be a very good stuff. Heck it is good stuff.

Moral of the story is find yourself a factory roller block and spend the extra $ in the first place. They dont make good flat tappet products anymore.

360 cam vs 318 cam is there any differences between both stock cams ..my 360la has a 318 roller in it I’m currently rebuilding wondering if I should replace with an original stock 360 roller cam

hey Tim what is it that you do sir for a living if i might ask.

Okay then I have a question, I have an old 5.2 magnum 318 out of a 96 ram 1500. I changed the stock cam out for a flat tappet mild cam. Will I be able to run that setup even though originally I had a roller lifter n cam setup?

I'll never run a flat tappet Cam again!!

flat tappet cams need zinc during break in

Hi hey you do lots of video on sb and poly dose anyone publish a rebuild book on poly im having a hard time finding one
