The core design
Most cam companies use modified factory camshafts or skimpy OEM
copies and then regrind them. Most of these end up being marine 12v
cams with the long bolt or Common rail cams that have to heavily
modified to make a performance grind fit on the cam. This usually ends
up with the cam being too narrow, too soft or both! We have the
BEST cast billet on the market, guaranteed! Don’t sacrifice
putting a $59 12v cam in your expensive engine or worst yet a re-grind.
Our Cams Feature:
- 1.020” wide lobes (widest in the aftermarket)
- Thicker core
- Radiused core
- Every cam is drilled and tapped for a bolt on retainer
- The ONLY improved design cast cam on the market
Shop around and ask others how wide their lobes are. If they say
their cam is made just for them, ask them if their name is cast into the
cam. I bet you it isn’t!
Dodge 1998-Current
This cam came about after I couldn’t find a cam that did exactly what
I wanted. Other cams worked well for towing but lacked major
performance gains at higher RPM. Some cams showed marginal performance
gains. Other cams spooled good but compromised efficiency to get the
chargers lit. All the others were either old gasoline profiles that
didn’t work well on the street or skimpy regrinds that were just a stab
in the dark. Generally shrouded in secrecy, it can sometimes be quite a
task to make an informed decision on diesel engine parts, especially a
camshaft.
We are here to inform you so, look at all our specs. If you don’t
like what you see look at our custom cam page or call us. Still not
happy? Ask the competition for all of their specs and see how we
measure up. We are here to get you the absolute best cam for your
specific truck, the first time.
After one year, and 50 cams, we settled on this design for our
flagship camshaft. The 181/210 is our standard camshaft for the B series
Cummins. 181° .280” intake, 210° .307” exhaust. This is the cam that
the factory should have come out with from the start. It 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 a 28 to 40+ hp increase trucks using this cam with. It is
forgiving on engines with high drive pressures. It is the best all
around cam for street trucks with occasional track use and 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, piston protrusion, and valve face depth.
Keep in mind that some Cummins cam gears have slightly different
offsets built in. We suggest you inspect your tappet for wear. If they
are worn either get them reground by Colt Cams, or get new ones. 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 or over 500hp we also suggest 110lbs 24v
springs or our 165lbs 12v springs springs and Hamilton pushrods. Follow
Cummins installation instructions, use adequate assembly lube, and add
some of our zinc additive prior to startup, to ensure no break in damage
due to the new low zinc oils on the market. 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 centerline, use Mopar performance offset keys
part# p4349650. This offset key kit comes with 1°, 2°,3°,4° and 5°
offset keys. 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.
Use the 181/210 cut on a 105.5LSA for best efficiency and the 181/210
on a 107 LSA for better spool for racing with larger turbo chargers.
