So i'm building a 440 and have a question about the hydraulic cam install. What holds the cam in place? Just the timing chain? I got a double roller chain, but thought i would check to see if there is a need for a button or anything to ensure that it doesn't move over time as the chain gets some slack.

thanks

The oil pump drive gear thrusts the cam rearward when the motor is turning.
The back of the cam sprocket is the thrust face, that rides against the front of the block.
No thrust buttons etc..
