ARP Expands Coverage Of Vintage Engines

While ARP’s engineering team is constantly developing fastener kits for late model engines like the Chevy LS/LT, Ford Coyote and Chrysler Gen III Hemi plus related aftermarket block/cylinder head combinations, they also step back in time to meet the needs of enthusiasts. Such is the case of ARP’s new head stud kit #151-4002 for 1927-31 Ford 201 c.i.d. Model A 4-cylinder engines. The kit includes 8740 chrome moly studs, parallel ground washers, and forged, hardened, CNC machined and polished stainless steel acorn nuts.

ARP also offers five kits for Ford flathead V-8 applications that cover various blocks from 1936-53 with factory or aftermarket cylinder heads. For inline 6-cylinder Ford applications (1965-96) ARP offers head stud kits for both 240 and 300 c.i.d. engines.

All studs for vintage applications are manufactured in-house at ARP’s California facilities from premium grade 8740 chrome moly steel that’s nominally rated at 190,000 psi tensile strength and significantly stronger than the OEM hardware. Threads are rolled after heat-treating, which gives them a fatigue strength up to 20-times better.
