High-Torque Camshaft for GX340/GX390 & 420/440 Clones

The OEM camshaft on our 460cc Engine!

Our Custom Grind camshaft is the result of many R&D hours testing what the big block engines like. Cams require Chromoly Pushrods, HD Valvesprings and a Billet Rod. DO NOT TRY TO RUN A CAM WITH A STOCK ROD, the journal will oval out and cause the rod to fail and most likely take the crankshaft with it.

Our cams are cut on a close base circle to the stock cam so the compression release is still functional.

246 Duration, .260" Lift, 110 LSA

This cam produces power from 1800-5000rpm and gives a drastic improvement throughout the entire RPM range. Recommended for Golf Carts, Mud Motors, Short Track Go-Karts, Marine and Pulling/Towing applications where a broad powerband is a needed and loss of low end is unacceptable.

This cam is easy on the valvetrain and will not "beat up" your valves or lifters. Originally designed as a "cheater" cam , its great for those who are running in a go-kart class which requires stock valve lift.

Add 1.3:1 rockers for some additional top-end kick!

Hi-Torque Cam Fits a Lifan 420 December 4, 2015
Reviewer: Jerry Gable from Pelion, SC United States  
This cam really does provide more power from idle all the way to 5000 rpms in my Lifan. I did crack a stock rocker arm when I hit 5400 rpm so I have ordered some Honda branded rockers. I have heard they are better. We will see.  No piston to valve contact. Still have good compression. Rocker shaft is fine.  Just a weak or flawed rocker arm. Tech support said they have never broken a rocker arm but I see posts on other sites where some stock rocker arms have broken. Hoping I do not have to go to billet rocker arms. Still, not the cam's fault.
