Can I use Erson Hyd lifters part # E914641 in my new MP 426 Hemi block?These lifters are for the 413/426w/440 RB, according to the Ersoncatalog……


They will fit and work okay. But you should know that all Hemis were factoryequipped with lifters 0.0005″ smaller than wedge lifters. This was done toimprove high-RPM oiling, but results in less low-RPM oil pressure due to theincreased internal “bleeding”.

Since you said “hydraulic”, I doubt that this engine will see a lot ofhigh-rev use. So the bottom line is: use ’em.
