These pushrods are machined in Erson's own Nevada plant to their own
strict specifications. Erson uses only the best special-mill run, 4130
hard-drawn steel tubing. Other, cheaper materials are available.
However, only aircraft-grade 4130 alloy delivers the strength and
durability to withstand the higher valve-spring pressure and RPM
generated by today's high performance and racing engines.
Specifications:
- Manufacturer: Erson Cams
- Part number: E91707 from the Erson "Brute Power" line
- Set of 16 pushrods
- Application: Mopar (Chrysler, Dodge, Plymouth) 383-440 CID Engines, 1958-78
- Diameter: 3/8"
- Length: 8.575"
- Can be used with or without guide plate
- NOTE: Erson identifies the length of ball & socket pushrods as if the ball is in the socket end, thus these actually measure shorter than the stated length by half the diameter of the ball (~1/8").
