The Torque Cam - Massive Amount of Low End Power for Marine, Mini Bikes, and Small Tracks

With approximately .280 lift and 220 duration (at .050), this is a nice cam that works well on both stock and modified motors. This cam produces lots of low end torque. One of the best all-around cams we offer. Works with stock, bored, or aftermarket carbs.

0411 TQ Grind - Serious torque for small tracks. 6000rpm maximum. 9-to-1 compression or more. HD springs required.

0811 RPM Grind - The best all-around cam for big blocks. 6500+ RPM. 10.5-to-1 compression or more. HD springs required.

0211 Marine Grind - THE ULTIMATE TORQUE CAM. Special grind for marine and winch boarding applications. Extreme torque. Designed for 2000-5500rpm. 11-to-1 or lower compression ratio required. HD springs required.


*Note: Block or crankshaft may require clearance to clear camshaft lobes.

Fits Honda GX240-GX390, 420 Predators, 460cc OHVs, and most other 9-15hp Honda style OHV motors. Will not fit 414 LCT motors or some 301 Predators with large journals.

Any camshafts not boxed on the shelf may take 1-3 business days to finish, grind, and ship.

5 of 5 AMAZING TORQUE AND NICE TOP END IMPROVEMENT! March 6, 2025
Reviewer: peyton zahnd from AL,US  
This cam makes GREAT power! machining quality is very nice! I'm running a 390 bored to a 407 on a stretched bt200, with 10in DWT rims and 22in tires and has no problem doing power wheelies above 20mph! I'm running aggressive style tires and from a dig the engine will light the back tire up instantly! And launching on pavement... good luck lol. I can plank over the bars, and it will still try to backflip! But if you really want to feel the power this cam offers, you got to have a billet flywheel! the extremely heavy stock dumbbell robs the engines responsiveness and makes it real sluggish, but it does tame the power delivery, if that's something you can benefit from! don't be scared to run the stock flywheel if you are on a budget though!! the stock Honda flywheel will not fail!!
thanks NR RACING!!
