Re: From a solid roller to hydraulic roller

This is hitting closer to home Mike. Is there a significant change one way or the other with an aggressive profile like like your EHR series vs your regular hydraulic rollers when taking the same .050" numbers into consideration? That being shorter seat timing yet the same 050" number. Not really, ...

Re: From a solid roller to hydraulic roller

So, what has changed. The thinking at Crane cams, it seems. And their thinking, sent Crane Cams the way of the dinosaurs. There is no "tight" LSA, and there is no "Wide" LSA. There's only the correct or incorrect LSA for an application. Almost all our circle track SBC cams are on an LSA between 104...

Re: From a solid roller to hydraulic roller

Amazes me with silly blanket statements such as 'wide LSA flattens tq curve'......when real world testing proves otherwise. Three examples come to mind: - Richard Holdener's LS dyno test 2 1/2 yrs ago of identical cams except for LSA. 108,112,120. The 108 made best low end tq AND best hp. It was eq...

Re: From a solid roller to hydraulic roller

If someone cant prove it then they probably don't have any idea WHY. With all due respect... With all due respect, when you've proven something, thousands of times, over 40+ years, there's no need to prove it again. To anyone who knows anything about cams, the major issue with your cam selection, i...

Re: From a solid roller to hydraulic roller

so he put a Jones hydraulic roller in it. 241-248 .640 or so lift, on a wide 114 lobe sep. It idles and drives like a kitten, drives really well, and still made 730hp, tq is still a non issue, or I should say it's still an issue, because it makes a lot more at lower rpm, and it had traction problem...

Exactly. What it's lacking, is a broad, flat torque curve. With 540cid, peak torque isn't the issue.

No need, you have it all figured out.
I'm sure Comp has a "Thumpr" cam that's just what you're looking for. :roll:

That's too bad. I wanted to see how well it worked for generating the lobe lift curve from the valve lift curve.
The system we use is accurate, but not the quickest or easiest.

Re: Camshaft lobe design by Billy Godbold

If some smart guy would only write a follower translation program that would produce valve lift from lobe lift, I would buy him (or her) a beer, and even dinner if it is an her. That's the exact opposite of what we use for design. We design the valve lift curve, and then translate it into the lobe ...

I highly doubt he's making as much. The Edelbrock Group doesn't not see the same value in Design and Development as the old ownership did.

He went out on his own, but I think he's still doing some work for Comp.
With how The Edelbrock Group is running things now, I think he saw the writing on the wall.

Re: Camshaft lobe design by Billy Godbold

Welcome to 1980.

For a top-tier racing engine, if the lobe profiles are not designed for a specific Bore, Stroke, Rod Length, port flow, and valve size, it's not optimum.
