Do you guys have pre clearneced bearings for this cam?

Asked by: John1019
Most camshafts do not require a pre-clearanced bearing. These are the recommended high performance bearings - https://www.jegs.com/i/JEGS/555/25401/10002/-1

i have a small block 350 if i put this cam in will i have to change springs and stuff also or can i put it in and just change lifters and that’s it

Asked by: jody36
Comp Cams states this cam requires a valve spring upgrade. While the stock springs may not coil bind at this lift this cam is designed with aggressive lobe ramps that work best with higher spring pressures than a stock spring provides.
