I have built many many flat tappet engines. Most dirt classes don't allow roller lifters. Break in is a personal preference. I have actually put engines in car, set the timing and break them in making laps at 7k. When parts are good and assembled correctly, stuff goes well.

Love the information. I have always known it was crappy machine work. I saw a SBC flat tappet cam from Comp 2 years ago that a customer wanted me to put into his engine build. With the cam properly installed in the block, half of the lobes were in the exact center of the lifter bores. Half of the lifters never would have spun. I pulled that cam out, put it in the box, and had the customer order a cam that was a better choice for the application anyway from Isky and send that Comp cam back. So go figure on Comp Cams selling and marketing junk. I have had a set of their $$$ roller lifters fail. I put the set of stock 150K mile L31 350 Vortec GM Eaton lifters back in that engine after dissasembling them for cleaning and no failures in 5 years spinning 7,200 rpm. I also bought the last cam I will ever buy from Comp about 3 years ago. I always had better luck with Crane when they were around. I had specific lobe numbers from their lobe catalog, the cam core type and everything ready to have a custom grind made. Their cam engineer practically refused to grind what I asked for and changed up the grind I had in mind. Basically decided I needed a dual pattern grind with 10* more exhaust duration than intake duration and decided since it was a 383 with a 2.02 valve it needed an even tighter LSA. I should have called another vendor because I failed to realize he added nearly 20* of overlap at 0.006" to my original target. Needless to say that cam is horrible, lacks off-idle power and drinks fuel at lower rpm. I changed it out for a custom Erson almost identical to the original specifications I wanted from Comp initially and guess what, runs the way it should.

@@powellmachineinc i brought my completely rebuilt (by a well known boat racing engine builder) 489 to a shop in michigan after it dropped a valve. that’s when i learnt there’s way more to it than what people think. anyone can build a motor to last for 20 years of 8 seconds at a time, in a boat it’s a different ball game. the amount of corrective machining on a motor that was just rebuilt is amazing. manley racing valves that say made in the USA were made in china. turns out you have to know where to get the real ones because they look almost identical. my block never had the mains line bored, they were way out. it was decked before but not on the same plane as the crank. one side was tipped ahead and leaned out the other side was .010 tipped back and leaned in. deck height from crank center obviously out a country mile. lifter bores might as well been bored by ray charles. long story short when someone asks me how much did you spend in your motor 10k in parts and 4k of machining to make sure they stay inside the motor.

It’s a grind and geometry issue. The cam and lifter must no only have taper but that taper must sort of kinda match. On my Rhoads Lifters I could see where the machine went around the radius of the lifter l, cutting and swirling it to a peak at dead center. I’m no machinist or a metal expert of any kind. But, you can literally see when it right. Then rock it on a clean piece of glass to verify taper, then measure. Then run it. And that one in the video is clearly not right. You have to inspect and measure literally everything. It’s the only way to know.

After everything came back from the machine shop I got it together and got all the right assembly oils and break in oil and once it was started I set the card at correct rpm and it ran for a while and once the break in was over it started missing and I did a compression test and removed the valve cover and noticed the pushrod was loose so I pulled the intake and found two lifters a lot shorter and they wouldn’t come out. So I drained the oil and saw metal in the oil and I just said forget it. It is still sitting in the garage.

The average builder doesn't have the tooling to measure the crown. Finding true N.O.S. lifters is hard to do and if you need anti pump up? I have a very mild hydraulic flat tappet cam running but its not right. Going to have to come out but the truck needs to be in service nearly 7 days a week.

Comp billet is no longer made in USA. It may be ground in America, but the blanks are the finest chinesium made steel. I quit using Comp 10 years ago. I use HOWARDS, only.And high zinc oil, not regular oil ,with one bottle of break in additive.

I wonder if it's always been like this or we are just more aware of it due to the advent of the internet? Are lifters really that difficult to manufacture accurately?

What exactly is out of center? What do you say the cam end of a lifter should be?

A flat tappet lifter is not flat. It is ground slightly domed at the end that rides on the cam lobe surface and it is engineered to spin in the lifter bore as it rides through lift and close cycles on a very thin layer of oil. The one he shows in the clip that very slight dome was very off center. We're it to be used it may not have ever spun in the lifter bore. And wiped out a perfectly good cam in short order and more.

SCARY! Off-center grinding means it may not rotate and kill the cam instantly. You may have singlehandedly solved the great cam/lifter epidemic mystery. What do you charge to true up 12 flat tappets?

I don't think they care about the problem when companies can get so much more money for a roller cam set up. Yes some say its not much more expensive, but it is. Cam costs more..lifters cost up to 3 times as much. Valve spring upgrade cost more and on and on.

I get that Comp Cams didn't manufacture the lifters themselves. I know who did. But here's the thing. I restore cars, mostly the body panels and frame. Let's stay simple: Suppose I do a hood for someone, I agree to do it for $400. Some chips, a dent when the guy gets it back it's straight as an arrow, the color matches it has two coats of clear and a one year warranty. My name is on it. The guy gave me money and he trusted me. Now say I used some cheap ass primer, and in 5 months the paint pops off. Guy comes back mad at me. Do I say "Sorry. The primer sucks. Go away"? No! That whole hood has my name on it! Not just the labor. I have to fix it. I may have to switch to another primer or do something differently but the guy gave me his money and trusted me so I have to do the right thing. I did NOT manufacture the primer or products myself, but I accepted responsibility for that whole product. I am the expert. Comp Cams are the experts. People go to them and pay NOT to have these problems. Last thing: Thank you so much for YOU doing the right thing and showing this, and doing it with some tact. People need to know that this is happening and a lot of them are doing the correct cam break in and it is not their fault. A lifter may not wipe the cam the day of break-in. It is often a little short while later. Cam break in has to be done right, but if the lifters are not shaped properly it won't do much good. You are doing a HUGE service. THANKS. !!!!
