Brilliant all round performance road cam. Smooth idle, pulls from around 1,200 RPM. Small gain in low end, big increase in med and top end. Unbeatable for genuine fast road use. Rev band 1,200 to 6,500/7,000 rpm. Intake duration is 260 degrees, exhaust is 268 degrees, lift at cam with 1.25 ratio rockers is .320" intake and .330" exhaust.
See MDM266/KIT for the whole kit and.... lifters, springs, and lube.

Excellent urban cam, pulls from very low down, increases low, mid and top end in nearly all engines. Smooth idle, and good economy. Rev band up to 6,000 rpm.
This Kent 256 slot-drive, reground cam is a modern equivalent to the Cooper S cam, with 254 duration and .320 lift.
There is no faster way to wreck a new cam than to use it with old lifters. For new lifters see 2A13 (stock 46.1g), AEG548 (46.5g with oil hole), C-AEG579 (40g, oil hole). See MDM256/KIT for the whole kit and.... lifters, springs and lube.

Many cam profiles have been tried over the years but the famous old "649" grind is still considered the best overall! It's a 300 degree duration cam with a valve lift of .470 when used with high lift rockers (.4" with stock)! This profile works great in everything from 948 to 1275cc motors. Todays standards would call this a mild race for a 1275cc, but a super cam for a 948cc. This is "slot drive".
Timing: Intake Opens 43°BTDC, Closes 64°ATDC, Exhaust Opens 61°BBDC, Closes 40°ATDC. Lift with std ratio rockers is .323", cold clearance .016".

When used in Sprites, Midgets, and Morris Minors a slot drive oil pump is required.

Slightly lumpy at idle, especially in small bore units. Strong mid and top end power. Rev band 1,500 - 7,000 rpm.

Hottest road usable cam. Not a good traffic cam. Lumpy idle. Not very suitable for small bore units unless fully prepared with big valve head. Very strong mid and top end power. Rev range 2,000 - 7,500 rpm. When used in Sprites, Midgets, and Morris Minors a slot drive oil pump is required.

This is possibly the ultimate street cam for any car. Also great for autocross or Vintage racing. Power band 2000-7000RPM. If you've done your reading, then you know that "Scatter Pattern" cams are designed specifically for the peculiarities of the A-Series engine with it's five-port head. By optimizing lobe centers and phasing for each cylinder, improvements have been made in torque and bottom end power. The result is much better driveability in a very high performance cam. These Kent cams are sold outright, no exchange.

The high performance camshaft has been specially cross-drilled for improved oil flow and longer life.

Race camshaft! Needs free flowing exhaust manifold and system, high CR. Mid- and top-end power only. Gives very good results when twin SU's have to be used. Rev range 3,250-8,000/8,500RPM dependent on build.

"Scatter Pattern" cams were designed by David Vizard to work best with the pecularities of the A-Series' siamese intake ports. The 310 scatter pattern is the ultimate race cam. Needs fully prepared engine for good results - high CR, high flow head, exhaust manifold and system. 310 duration and .420 lift
Lobe center is 106 degrees.

Advancing the cam timing moves the valve opening and closing events earlier in the cycle. Since the relationship between the intake and exhaust lobes cannot be changed, advancing or retarding a cam affects both the intake and exhaust valve equally. Also, the most important thing advancing or retarding a camshaft affects for engine power is when it closes the intake valve. For example, if the camshaft is advanced, the intake valve closes sooner. This typically increases cranking compression on a high-duration race cam. The result is more torque and power in the lower rpm ranges. But as the rpms increase, the velocity of the air/fuel charge in the intake ports also increases dramatically and the early intake valve closing hurts power.
