Don Terrill’s Speed-Talk

Since no one has any real data on these, I'm going to lock this thread, until someone actually runs them.
It's not a "Game changer" until they're proven to work.
Right now, they're just a sales pitch.

So one is swapping a cam to suit the existing converter and the other is getting a converter to suit the cam. Which is it? That's up to the OP to decide. If he wants to turn it 6,500+RPM, keep the Comp cam, and change the converter. If he wants to only turn it to 6,000-6,200, and be more street fri...

We developed the tool steel cam and DLC coated lifter deal in 2000. It was a true game changer in the cup world compared to the stelite overlay/chilled iron lifter we used for years. Virtually eliminated cam and lifter problems. The cam cores alone are 3k. Yes, and like many other NASCAR innovation...

The shorter duration cam on the wider lobe center(106 ICL-114 ECL) will have a flatter torque curve, and still hold on to the top-end power.

I need a little advice as to if it would be worth changing my cam. I have a comp cams XR294HR hydraulic roller in it, still on the engine stand. That cam will make peak HP at 6,400-6,500rpm. If that's where you want to make peak power, then run it. Usually, with a 3,000 stall, I put peak HP at 6,00...

He's never ground a cam in his life, not has he ever designed a cam.
He buys cams from Companies like Bullet, Comp Cams, and Clay Smith cams, and sells them at a huge mark-up.

Believe it or not but I ran a set of tool steel dlc lifters on a iron solid flat tappet camshaft and it never damaged the cam are the lifter.And it had 200# of seat pressure on it 450 open.And I broke it in with a set of ceramic foot lifers first,and I was shifting at 72-7500 rpm 78-8000 at the str...

DLC coated lifters do not hold up well against cast iron cams. We tried that, decades ago. It does hold up against steel cams, but there's no way in hell that they can sell a set of DLC coated lifters, for $120. No matter what material the lifters are made of, they have to be micro polished, before ...

One thing Comp has, is a serious advertising budget. In 2006, HOTROD magazine did a multi page article on my cam balancing system. Wasn't isky the ones that went to print slamming your lobe designs here; https://iskycams.com/tech-tips-2000.html#2007 Was there a rebuttal from Jones Cams? I wouldn't ...

Surprised they haven't tried to buy you and your designs outright Mike. Vic Edelbrock tried.He wanted to buy the company, and pay me to run it. He was willing to pay me what I wanted, but started off by offering me 10% of what he was willing to pay. I ultimately turned him down. I figured if he was...

I was at an aviation museum recently and they had some fantastic cutaways of some engines. The Wright R-2600 has a roller cam, roller rocker, and hollow sodium-filled exhaust valves - this engine first started up in 1935. The Allison (so General Motors) V-1710 was SOHC, 4 valve per cylinder, with a...

The vast majority of the new LST lobes have more area on the back side of the lobe. Are yours that way as well? My Asymmetrical I.R Series, and my AK435 Series are all that way. The First one I designed for the Asymmetrical I.R. series was in 1988 I have multiple other profiles designed that way to...
