Overview
An iron drive gear on the shaft sets which camshaft this MSD Pro-Billet distributor can run with, and the small-diameter body is meant for tighter engine bays. The listing gives only the title, a name and a short set of specs.
MSD offers the distributor in a billet housing with an iron gear, and the small diameter is its stated feature. Fitment, ignition type and advance details are missing, so the buyer has to verify everything that matters before ordering.
Who it's for
A builder with a matching engine and camshaft can use the part number to confirm the swap with MSD. Anyone buying from the title alone should check the listing gaps first, because the material row even reads plastic.
Pros and cons
- Small diameter body
- Iron gear for cast-iron camshafts
- Clear part number
- Vehicle fit not listed
- Ignition and advance details left out
- Material row reads plastic
- Warranty terms vague
Performance notes
The gear material has to match the camshaft or wear shows up fast, and the body diameter decides whether it clears nearby parts. The listing gives no advance curve or signal details, so ignition behavior cannot be described here.
