Most cam companies use modified factory camshafts or skimpy OEM copies and then regrind them. Regrinds often expose the softer material of the camshaft core that is more apt to fail prematurely. Don’t trust a regrind in your diesel engine. We use only new blanks for our cams.
Recently we redesigned our full line-up of drop-in and custom cams. In the past our 181/210 had .279” intake lift and .307” exhaust lift. We have recently raised the lift to .290” intake and .320” exhaust as well as reshaped the lobes and changed the centerlines. You will notice a more crisp throttle response, more power, less smoke and lower egt over our old 181/210.
Our Cams Feature:
Our 181/210 spools great from right off idle and makes good power to just over 4000rpm. On trucks that are over fueled you will see a drastic reduction in smoke and EGT. We have seen 25-60+hp increase in trucks using this cam over the stock cam. It is forgiving on engines with high drive pressures and is the best all around cam for street trucks with occasional track use. The 181/210 does not sacrifice torque efficiency or fuel economy for spool up. Works best when the intake is installed from 98° to 100° centerline. You should not need to fly cut the pistons; however it is up to the customer to insure installed centerlines, and piston to valve clearance.
Keep in mind that some Cummins cam gears have slightly different offsets built in. We suggest you change your tappets when installing any of our cams. If you are installing this cam in a 12v please replace factory tappets with tappets from a 1998-2002 24v for best longevity with low zinc oils. On engines seeing over 50psi, over 500hp, or over 3500rpm we also suggest 110lbs 24v springs or our 165lbs 12v springs and Hamilton pushrods. Follow Cummins installation instructions, use adequate assembly lube, and add some of our zinc additive prior to startup. Always keep the engine from starting until you visually verify that oil has made it all the way to the rocker arms.
To modify installed centerlines call us for offset keyes. Just remember 1° camshaft is 2° crankshaft since the crankshaft moves twice the speed of the cam. A basic degree wheel from Jegs or Summit, a small amount of wire and a dial indicator is all that is needed to degree a cam in. If you don’t see a cam to suit your needs, call us!
Here are some of the benefits you will see with our cams. Results will vary depending on the grind you choose.
- More duration
- Lower EGT's 100-250 degrees
- Faster spoolup 100-200rpm
- Bolt on gear option
- Better Fuel Economy 1-3mpg
- Major reduction in smoke
