Any Valvoline users running solid flat tappets?

I didn't want to distract the thread from my main point detailing Brent's irrational fear of installing a solid flat tappet cam for any reason, under any circumstances, and at any price. Likewise, I don't want to distract ERAChas with euclidean geometry.

I regularly saw 18 to 25 HP improvement with same spec cams on DTS dynos. SBF, SBC and BBC up to 600HP builds. Juice rollers, were SOP from 600-650HP builds and soild rollers the only choice from there to 1100HP.

Actually, you're more entertaining than the rodeo clowns
that normally distract me...

Doug, search some other forums if you want to get a second opinion. You can probably search this one as well, I think I've heard Keith Craft say the same thing.

The key here is that you can't really have the EXACT specs between a flat tappet and a roller camshaft. The .050/seat durations and the lifts may be simliar, but the weight of the lifters, the ramps needed at open/close, etc., cause the lobes to be designed differently. The amount of horsepower that you can get from a swap can be significant.

Brent
I'm no expert. Wouldn't even think of building my own FE. I'm just bustin' your balls. I look forward to your posts, and consider you an expert.

And I know you can't get two cams exactly alike, one for a flat tappet, and one for a roller. Which is why my BS buzzer went off. Ya can't make that claim, 'cause it's not possible. But there will be those who try to convince me......

I guess anyone who still is searching for a haberdashery and has fun with “Euclidean” geometry should have a flat tappet cam. After all, assuming a small set of intuitively appealing axioms, and deducing many other propositions from these would be the very essence of Euclid himself and would lock that person solidly into a pre-theory of general relativity era. Right where a non-roller type needs to be! You know, ignoring gravitational fields and so forth with the strength of a dino-motor!

No, a solid roller.

Just kidding. ;-)

This was a complete 4V closed chamber motor that I got for $250. ;-) It will be some cheap fun for the summer, bored/honed with torque plates, valve job, crank polish, new rings, bearings, single plane intake, and an el-cheapo custom grind flat tappet cam.

Going in front of a 5-speed and a 4.30 rear gear. Should be fun.

Next year it will get a real cam. ;-)

OMG, and oye vey, I just quickly read through this thread.

Here's my assessment.

Brent 1
Patrick 0

Patrick probably still uses Windows 95.

I remember my boss years and years ago saying that "this Internet thing will never take off."

Patrick probably still sees the brick and mortar video rental store as a viable business model.

Patrick probably still uses stamps for his mail.

Patrick probably still uses Kodak film and then runs down to the local drug store to get his film developed.

Patrick probably still thinks Joe Theisman and John Riggins play for the Washington Redskins.

That brings back wonderfully fond memories of sitting in RFK with my dad watching those two play. Everyone hated Theisman, but you loved to hate him -- and I can still see the play that ended his career. And when Riggins took his bow, man I could just go on and on. It's just not the same since they moved out of DC.

[patrickt]

Yep, I remember it like it was yesterday:

I remember that play clearly too, just like it happened. I can't watch the video, because it still gives me the chills.

I was sitting in the stands, upper deck behind the goal posts on the left side of the tv cameras' view. You couldn't tell what happened -- and even the announcers on the little transistor radio you kept in your ear didn't know, but you knew it was something really bad because LT was going nuts. Then there was a guy a couple of rows down that had a little tv... and the word spread rapidly.

If the player that broke the leg was not on COKE, would this have happened?? The TUNA always protected #56. That was no way for Joe Thesesman to end a career. O buy the way, did you know Good old Joe's name changed to rime with Heisman? Lived 1 town over from me growing up, The whole town Hated him. Married the hottest woman back then and that failed. Drew Person never forgot his roots or where he came from, (same town) and still comes home to visit and help out the football team. LT was great on candy, to bad he couldn't do it straight. Rick L.

Not to drag this back to oil ZDDP levels or anything (not nearly as interesting as watching Brent and Patrick spar), but I found this posting on Valvoline's VR1 20w50 racing oil. VR1's ZDDP levels aren't high enough either and it was tested twice to be sure:
