136-S:
Street & Off-road; excellent low-end response; 1500–2180cc; 280 degrees; 0.415in lift. Timing: Exhaust 70°/30° – Inlet 34°/66°

141:
'Not very streetable but good for the strip' (Deano's words!); large cc; 302 degrees; 0.443in lift

141-D:
Full competition grind; requires 1.4:1 rockers; 342 degrees; 0.500in lift; Timing: Exhaust 101°/71° – Inlet 65°/97°

Hope that helps... Smiley

One more question.

My engine is based around:

82 SPG crank
88 Piston/sylinders (ccm 1995)
DDS 136-S camshaft
Original heads with 40/35.5mm valves (ported)
42 DCNF carbs

What kind of ratio rockers are suited for this engine? This will be a street/daily driver only.

 the most practical would be your stock 1:1 rockers with some good swivel style adjusters as the cam in question is a quite relative small cam designed for bottom end torque and good driveability. You could go to 1:25's also with good results as well providing you have some port work to take advantage of the extra lift.   good luck..!!

You will love the 136S with that motor combo. Lots of great mid range power where you do most of your driving.
