340 lifter bores bushed or not ?? Solid Roller cam

How hard are you running it compared to the next guy! Lol
Pretty sure when anyone commits to a solid roller they are going to be running it hard.


You would think so, but not many do.

The lobes out there today are so aggressive that the small wheel just can’t keep up. The other factor is the cam core and base circle size.

The chrysler has a bigger cam core and base circle (it should anyway) so for the same lift, the chrysler lobe will be bigger. IOW’s, to travel the same distance in lift, the wheel has to cover more feet per minute. That ups the wheel speed a bunch for the same lift and RPM as a chevy core.

That means the wheel speed will reach critical on the Chrylser before it does on the chevy. And wheel speed is a parts killer.
