Here are some more information for Billet Roller Cam:
A stainless steel tube is basically a closed shaped structure which is used in numerous structural functions. The shape of a stainless steel tube can be round, square or rectangular or as per the requirement of manufacturing a particular application. A 1 inch of round tube has 1 inch outside diameter whereas, a 1 inch round pipe has 1 inch inside diameter. The reason behind this is that the external parts of the tubes are important in building structures and the internal parts of the pipes are important in the flow of fluid.
There are mainly two primary types of steel tubing: seamless and welded. The latter begins as a flat strip whereas, the former starts in a melting furnace.
1. Seamless: Primarily the manufacture process of a seamless tubing starts from an electric arc furnace. The steel is later cast in an ingot or cast repeatedly as a bloom. The latter is then rolled in a billet which later on becomes a tube by being drawn over a piercing tool with the help of two external rollers. These rollers are set at an angle to each other which help to move the billet. This is the point when a "rough" tube is formed. Then it is put in an elongator, inside which, with the help of three rollers and an internal mandrel the tube is given a final outside diameter and wall thickness.
2. Welded: This type of steel tubing is made out of either hot-rolled or cold-rolled steel which is poured in the tubing manufacturer in coils. If required the coil may be processed to remove unwanted scale and improve finish. Then the coil is passed through grooved rollers till the shape is formed and the free edges are properly shaped for welding. The external and sometimes the internal welding residue are removed after the edges of the tube are butt welded together. After all this procedure the tube is made to go through two semicircular rollers that help to bring the tube to its final required dimension.

Precision Sheet Metal Fabrication
Metal fabrication is a process of producing a metal component by modifying a raw piece of material in a machine shop. These materials are processed on different temperatures and depending on the range of temperatures; the process is classified as cold, warm and hot. Precision sheet metal fabrication describes various different processes that form sheet metal into finished products. Objects that are fabricated and used for machinery and other instruments are among the daily used objects like paper clips, computers, bolts, nails, automotive parts and many more.
There are various factors like rate of production, desired geometry, and other physical requirements that influence the fabrication process. The benefits of the metal fabrication process are far and wide because it is used by all industries. Every precision sheet metal fabrication process undergoes three primary processes that include forming, cutting and finishing. Forming is a process that alters the form of the flat metal sheet. Forming can be done using various different processes like annealing, bending, cold rolling, drawing, forging, mechanical working, press forming, roll forming and welding. After forming, a metal sheet is cut to alter the shape by removing some unwanted material. The cutting process includes stamping, shearing, sawing, drilling, blanking and punching. Finally, the last stage is the finishing process. In this process, the shaped metal sheet is given a finished and soft surface using sanding and vibration techniques. Aesthetic considerations like painting and visual design applications are also few of the method applied to give the finishing touch. Some of the latest techniques in metal fabrication involve laser cutting, electro discharge machining, water jet cutting and wire cut EDM. In some cases CNC machining is also used.
There are various products that are created during precision sheet metal fabrication. The most common objects produced are metal cabinets, enclosures, ventilation shafts, hoods, exhaust systems, tanks and prototypes. Metal fabrication is also used by various other industries for food dispensing, food storage, communications, automotive, computer, medical, electronics, aerospace, telecommunication, pharmaceutical, residential and construction.
Some of the types of Precision Sheet Metal Fabrication include processes like Annealing (heating), Bending (straining), Cold forming, Cold rolling (shaping sheet metal using rollers), Drawing (material is forced into a die with a punch to form a cup-like shape), Forging hammering or pressing), Rolling (reducing thickness of the material), Extrusion (producing cylindrical bars or hollow tubes by forcing round billets through one or more dies) and Spinning (forms axially symmetrical shapes).

What is the best overall cam for a 383 stroker?
I am thinking of buying a crate engine and the cam options I have Hardened Steel Billet Hydraulic, Roller or Solid cam. I want one that is low maintenance with maximum proformance. This is going to be a weekend warrior show truck. I am learning as I go with this project.
Hi Rob,,,
Cam selection is one of the most mysterious aspects of building a performance engine.
It's Always been like that.
The amazing advances in the:
* Practical Knowledge/Experience gained over the years
*Modern engine,and engineering Science
*And,,Manufacturing Technology
....all seems to only Deepen & Widen the "mystery" of it all
All while ,,"everybody who has an ignition key to something with loud mufflers or shiny wheels is a CAM EXPERT"
A Hydraulic lifter cam is always going to be virtually "maintenance free".
I well recall the era when Hydraulic Cams were quite limited in the level of performance they could achieve.
The Reason was the Geometry and Dimensions of the cam's ramps and such which Physically restricted use of Hydraulics to some rather modest Physical Profiles.
There WERE some extremely strong running Hydraulics---
but they Stopped where Mechanical Cams Started.
Nowdays,,,It's COMMON for Hydraulic Profiles to yield Performance equivalent to "Impossible" in the LATE 70's/Early 80's.
Performancelevels that previously Demanded strictly Solid Lifters,,,and were considered fairly Radical Race cams
Roller Cams:
have always been Ultimate,,because they accomodate Physical,Mechanical DIMENSIONS that ANY flat tappet cam simply cannot handle.
PART of that is about Geometry
PART is about the Strength of the Valve Springs Necessary to Control the Valvetrain at extreme Dimesional & Geometric Profiles.
Simple concept---Rub 2 surfaces together compared to ROLLING one surface across the other.
Like comparing a SLED to a Wheeled Wagon.
Either may be Fine as the Other under a LIGHT load.
But when you're Limited to a Given Size,,,,and begin to VASTLY Overload the carrier,,,
The Wheeled one is a No Brainer choice....it actually becomes Necessary.
Anyway,,,,
In terms of Maintenance,,,Hydraulics win Hands Down.
And in Today's Age,,,
Hydraulics offer very Aggressive profiles yielding fairly extreme levels of performance.
And the Do that while maintaining Stability and Low/No Maintenance.
SOLID Lifters:
are always going to require periodic adjustments.
On a Street Engine,,it's absurd to endure the Effort and Expense and Inconvenience.
And the RISKS of letting the service routine slide "till next weekend,or 2".
Based on what you've stated your goal is,,,and what I know of such endeavors....
Scratch a Solid Lifter Cam OFF the List,and consider it does not even exist.
IDEALLY,,a Hydraulic Roller is "best of all worlds".
It offers Best of Both worlds---yet in NO way can it be considered any Compromise.
They're in a Class all their Own,,
They are STILL Hydraulic Cams,,,,but MEGA-Hydraulics due to the virtues of simply being Rollers rather than Rubbers.
It's possible to get More Effective,Efficient Designs with a Roller than any flat tappet.
So it's possible to get a Physically MILDER ,Gentler Mechanical Action,,,,which actually Fills & Clears the Cylinder BETTER than a "wilder profile" Flat Tappet cam.
More Performance from a less abusive mechanical action.
If You have the option of getting a Hydraulic Roller,,,that's Clearly No-Doubt BEST Choice.
It's More Expensive,,,and you Really Dont NEED it.
But on the Other hand,,,there's Some Value in it as merely a FEATURE to add to your list of SHOWTRUCK's Trix
Most Practical Overall,,
Low Maintenance,,,Reasonable Cost,,and just about any level of performance you can realistically USE on the Street.
"Plain Ol' Hydraulic" takes that honor easily.
I'd say the choice comes down to Either a Flat or Roller HYDRAULIC,,,
depending on your How & Where you want to spend your Budget,,,
and what actual price differences are.
Another suggestion,,,Don't get Over zealous when chosing a specific Profile.
Most common mistake is to OVER-cam an engine.
Many folks underestimate the Negative effects of too aggresive a profile for their application.
If you want to invest the Effort,,,
Contact a few name-brand Cam Grinders.
Be BRUTALLY HONEST about what you REALLY HAVE,,or Truly INTEND to have,,,,as far as every considerable parameter encompassed by Cam Selection.
That's Type of Intake/Exhaust,entire Engine Specs really,,Transmission,,Gear Ratios,Vehicle weight,,,,and how you Want it all to perform.
Get the PRO's recommendations on specific grinds for YOUR Actual set-up,,
and then compare them.
You'll probably be surprised at how similar their Reco's are.
FORGET about asking any Retailer or Vendor or Speedshop.
They are MERCHANTS,,,not Camshaft Engineers.
Though in all fairness,,Lots of Merchants know their stuff quite well.
Getting the Mfgr's Opinions and suggestions,,,
You can be very confident of getting a Cam that Works FOR you instead of against you,,,,and one that will meet your expectations.
And Probably EXCEED your expectations.
And Don't be Surprised when you find that YOUR Personalized recommended BEST/IDEAL grind is several numbers down the list from " Wildest thing " that'll fit in the engine.
Good Luck with your project!
