Thanks for that experienced explanation. Still not a cut and dry option though. Using race application components don’t fair well on the street when you are looking for low maintenance durability. The quest for power seems like a bit of risk disintegrating the engine- not just the cam. Old...

Is it plausible to break in the flat tappet cam with weaker springs since you will do the break in period at only 2000 rpm? That might put in a good starting position. That’s in the event you decide to use a flat tappet cam. I believe I saw someone comment on this before. I’ve been watching...

Thanks

As someone just entering the world of roller lifters I was under the impression that I was out of the loop by not ” up grading” to roller lifters used by car manufacturers today. Even a builder who assembled my 340 said I was the only one asking him today to use a flat tappet cam. Three pages...

Thanks for the comments. It’s those damn needle bearings that make me think is it worth the risk. Even the bushed lifters are not an easy out. They don’t have a long service life and break the bank. My Howard’s roller cam is .530 lift and is supposed to provide 13-15 vacuum but will the valve...

Interesting because I saw one comment about adjusting to .004 while cold. May I ask how long you have used the solid roller lifters on the hydraulic roller cam? Were they used as a street application? So when the engine cools down the lash increase? Does the engine make the noise till it...

That was the possible justification mentioned in the video for being able to use a hydraulic roller cam to do this because it’s design was not aggressive like the cam designed for a solid roller cam. Again these guys on Engine Masters had no experience doing it but heard about others were doing...

Appreciate the discussion. People have commented on YouTube claiming it’s been done many times. I was wondering if someone here had done it. Bushed lifters for $1,000 is beyond my budget…But investing a bunch into a build and have lifter failure is a larger loss. The lifters I bought are...

So I've been watching a lot of episodes lately of Engine Masters and ran across this episode that seemed like a topic that would be interesting if not already discussed because I myself am in the process of refreshing a 440 with a hydraulic roller cam with hydraulic roller lifters which makes me...

I will I’ve them a shout at Howard’s. Thank you

So these are a different animal.. I’ll do a bit more research. I’m trying to prevent another issue. If it turns out that the dyno test shows a problem it means changing lifters which means disassembly of the intake. More time. More cost….. Over four years now

I found my order. Turns out I did purchase the Howard’s lifters. I’ve seen a few dynos now mention problems with them at above 5500. Have you had any experience with them?

I will mention that for sure. I know he is removing the heads and I would think that visible damage or hits could be seen on the pistons. I’m not reading favorable comments on Howard’s lifters at or above 5500. I am not on location and can’t remember which lifters I bought. Paperwork is...

Just trying to make some sense without having the same background. Are these specs you mentioned @.050 lift? Any reason why valve lift is not there when cam specs are mentioned? Is lift not as much a factor? Thanks for chiming in.
