MGT-5200: This is a mild, torquey street cam that will give strong acceleration without being temperamental. The best power range is 2200-5200, and it will rev to 5800 RPM.  INTAKE: 17/49     EXHAUST: 53/3     DURATION: 246     LIFT: .316"

    Necessary mods: Can be used with stock springs if they are new. Must also have lifters ground and hardened. A slight compression boost will give additional power, but is not necessary.

MGT-5800: This grind is excellent for slaloms and vintage racing. The best power range is 2800-5800 RPM, with a peak of 6200. The cam delivers extremely strong acceleration plus high speed.  INTAKE: 22/54     EXHAUST: 58/8     DURATION: 256     LIFT: .360"

Spring recess cutter to enlarge the spring recesses in the head to accept competition springs  $75.00 --- (Refundable for credit less a $25.00 resharpening charge)

NOTES:

(1) Early model MG's (through '72) used a pedestal lifter and a short pushrod. Later models used a cup-type lifter and a long pushrod. The latter arrangement is better (and cheaper) and can be used on the earlier models if the pushrods and lifters are changed out as a set.

(2) PAECO valve springs have an outer coil diameter that is larger than the stock spring diameter, and will not fit down inside the spring recesses on top of the cylinder head without a slight enlargement. Our spring recess cutter will do this quickly and easily, using a 3/8" or 1/2" drill to power it. The cutter is refundable for credit less a $25.00 resharpening charge.

(3) PAECO MGA/MGB springs and retainers must be used together.
