Where have all the Magnum parts gone?

A few items I have been searching for:

MAGNUM HYDRAULIC ROLLER CAMSHAFT:
P5249663 (300hp)
P4876348 (380hp)

Comp cams have a grind that’s is super close to the 380hp.
The 300hp cam is a stock cam IIRC


HEAVY DUTY VALVE SPRINGS:
P4876062 (300hp)

Aftermarket springs will be ez to get

MAGNUM ROLLER TIP ROCKER ARM SET:
P5249800

Aftermarket units are cheaper

MAGNUM PORTED CYLINDER HEAD ASSEMBLY:
P4876257
MAGNUM R/T CAST IRON CYLINDER HEADS:
P5007140
P5007141
P5007145

ALUMINUM MAGNUM CYLINDER HEADS:
P4876624

Unobtainable new unless someone has them under their bed.
Use Edelbrock heads instead

MAGNUM ROCKER ARM SET:
P4876050

Answered above- aftermarket
M1 DUAL OR SINGLE PLANE INTAKES

Hard to find anything…

The only intakes currently made are the chink knock offs of the also available Edelbrock rpm.

But keep your eye out for what may pop up in the want ads and swap meets. Keep your bank account fat for an instant press of the “BUY” button.

MoPar has discontinued most if not all the small block program in favor of the Gen 3 HEMI engines. They did this a good while ago.
