Keep a check on the drivers site. A few weeks back, a guy was looking at having more roller cams built. Since it was by Natchi (spelling ?) and Don, that built the first batch, he asked if I'd help with a second batch. I said sure.

But, that's, so far...where it's stopped.

LSM will do batches of four. I bought an unground blank from Ted H. a few years back and that's who made his. I had Comp Cams grind it for me. It's going in a 471 supercharged motor. I would be interested in another blank if you don't want to invest in four all yourself.

Approximately how much for four?

Just asking, but since LSM claims to be a custom cam grinder, why did you send one of their blanks to Comp?

Phil Harris is working on producing roller cams also, but has a ways to go before they will be available. Cost is yet to be determined, as well as what grinds he will have them ground to. I don't think he will offer the choice of your own personal grind. I am on his list for one, but I'd be interested in someone else's efforts as well, the cost would always be a factor. Bill

I could get with the guys that did the first group, see if they are interested.
I know Don the grinder would be interested.
I'd have to find out the minimum quantity from them. I "think" it was 10, but not sure.

These WOULD be "one" piece cams.
We'd need to move the lobes around also..!

Jack,

I was planning on using Comp lifters. I had a good relationship with them with other cam work. I saw no reason to go to LSM. LSM was good at getting me information on the blank I had.

Phil Harris should soob be able to supply you with a nice billet steel camshaft.
I know he has been sent some, and some bronze (alloy) distributor gears are being made.
Phil has a source for grinding your profile.

Phil Harris at Fairborn Studebaker has a batch of Roller Cams I made and is in the process of testing them. I just finish machined a bar to produce distributor gears using SAE 65 bronze to run with the roller cams.

Sounds like you guys are making good progress on roller cams, I did find one roller cam made near Sacramento, CA so they will use that one to start the project, thanks Dave

FYI...
Just be real careful on the dimensions fore and aft on the roller cam positions.
A couple people have had roller lifter axle interference issues due to one roller being slightly off and the roller cam lobe was contacting an adjacent lifter.

Jack has done some nice work on his dyno cam sim program, and has come up with some numbers for us to chew on...
I asked him for a roller cam profile for a N/A 259 and 289 with solid roller lifter and a hyd roller lifter.
Also one for a supercharged 289 with solid roller lifter and a hyd roller lifter.
Thank you, sir!

What do y'all think about these numbers? :?: :?:

Solid or Hydraulic NA – 270/276 111.5 LCA 20-70 and 66-30 makes 330 hp @ 6000

Solid supercharged - 284/292 116 LCA 26-78 and 82-30 makes 464 hp @ 6500

Hydraulic supercharged 280/292 116LCA 24-76 and 82-30 makes 464 hp @ 6500

IIRC SN series.. 10 pounds +- (on the boost spec) Jack can confirm...

These spec's are to help determine a marketable cam spec for the 'common' Stude owner who wants to step up to a roller cam from an R2 R2+ regrind flat tappet. The spec's are not for a race engine, as that customer would have more/very specific parameters and spec's. Performance street engine, basically.
