Roller cam

I seen it a few times. On the quick, Comp Cams uses it. It serves more of a warning that the design is for a larger lifter since the rate of lift becomes more radical when you take advantage of the bigger lifter diameter.

Then there is the 1 inch diameter lifter and the mushroom lifter. You’ll find these in the back pages of the catalog in the race section.
 
Rather than a edit to the above;

I opened up my Comp Cams & Lunati catalogs and I did t find what I thought was there. (“904 lifter (usage) only”)

I have looked through the lobe masters section of cam company offerings before, which seem to not be in my latest paper catalogs. Search for them on line, the master lobe catalog section of a cam company.

While this is for the 426 HEMI engine only, other catalogs will list this or something similar for all the Chrysler family engines w/a .904 tappet.
 
Funny I read this thread this morning and later today the new episode of Engine Masters just dropped. Check it out. Single pattern vs split pattern camshafts.
 
TT5,
How did the s/pattern & d/pattern cams compare? Any numbers?

Split pattern made more up top and gave away a little down low. It reminded Freiburger of a single plane intake vs a dual plane intake comparison in how the curve was tilted.
 
Very mildly I’d say. Normally that dual vs single is a bit heavier in there spread.

Yellowrose would have said the same thing even before the episode started. Pretty much everything they went over on the show has been said here. The problem is finding it through out all the threads. I think it was a good episode.

Id like to see follow ups with stock heads for sure.
And even a wild exhaust duration am like a Thumper or a Rattler or Whiplash

I was always told there is a point of going to car on exhaust duration. I’d like to see where that is and know why on many levels.
 
And that is why I like SP cams & even reverse pattern cams for most applications: you are at 3000 rpm more often than you are at 6000 rpm.

That's who I'm working with as we speak. I got tired of waiting 7 months from Lunati. Jim is a great source of information, and is helping me with the correct torque converter, too. Thanks again, Rob.
