Switching from Comp to Morel lifters
 

When switching from Comp Cams 819-16 standard height roller lifters to the Morel Ultra Pro .300 tall lifters part number from PBM RL982 will the pushrods be the same or will i need a different length pushrod? Thanks

Shorter pushrods required and if you're running shaft rocker setup, you really need to measure for the correct length, not saying it isn't a good idea to measure even with convention roller rockers.

Zip.

You may need new pushrods but should ALWAYS check to be sure

I made the swap and the pushrods stayed the same.The pushrod seat location in the lifters measured the same between the two.

I know yours are .842, but what is the deal about the 1" dia units? They say the exhaust lifter has two sets of needle rollers. Is this a set inside a set? Dave
