great info as usual, I was unaware flat tappet technology was that advanced, very cool!

Valve train weight vs nose: note the billrt cam has a larger radius nose. This buys a little extra time with a gentler over the top profile that helps avoid some lofting/bounce issues on direction reversal. You give up a little peak lift and get a portion of that back as are under the curve.

Brent, awesome video ! I have a question. I know what you said at the end of the video about “ballpark” (?) valve spring pressures for the billet tool steel cam core as being about 220 lbs. seat, and 500-525 open. Is that open pressure set in stone ? The reason I am asking is because Comp has a dual conical valve spring that has 160 lbs. seat at I believe 1.900 or 1.950 installed with 600 lbs. open. Do you see where I am going with this ? Or would that not work ? I’ve wanted to do this ever since they came out with this particular spring. I am asking because I don’t know. And it would be better to ask someone that does- you, in this case. Either way, thank you for your time, video’s, and above all , sharing your hard earned knowledge with your subscribers.

What is the typical longevity of the DLC lifters paired with the billet camshaft? Is the jury still out? I really think that technology like this can open up some really interesting doors even with the degrading quality of modern metallurgy.

Before NASCAR switch to solid rollers, this was the staple of all Cup engines. The lifters and cam will last a very, very long time. As with anything else, it depends on the application, but my guess is that the cam/lifters would outlast most everything else.

Metallurgy is better than it has ever been. The problem is the cheap product manufacturer's trying to get steel as cheap as they can and trusting mill certs from shady mills. I work in NDT and Positive Metal Identification is one of the fastest growing markets. We are even being asked to check mild steel beams and HSS which no one would even have bothered with years ago. But now lots of places actually buy bulk lots from China that have been rejected and bring them in anyway and print you out a mill cert that says anything to make the customer happy.

Hi Brent. Cool stuff going on! Question on that FE cam for the 397 TP. Are you using a top oiler block? I don't see the #2 and #4 cam oil grooves for the rockers on the side oiler. And don't think it was mentioned yet? Unless it's 1 of the 2 things you have planned!! Thanks for all your vids. I pickup some great tips on many things. Very much appreciated!

What’s a ballpark price comparison? The DLC coated cam and lifters vrs standard stuff and the billet core?

A custom flat tappet cam is $275 and standard lifters are around $90-100. A custom nitrided flat tappet cam is $425 and EDM lifters are around $160. A custom billet core solid flat tappet cam is $825 and the tool steel DLC coated lifters are $1400.

@@lykinsmotorsports thanks for the reply. My custom 55mm solid roller billet was about 850, and .937 BAM’s were about 1400. So I can see the billet flat tappet being used for high end class stuff. The nitrided flat tappet cam and edm lifters is a solid alternative at those prices.
