I’m trying to get some real-world input on the Kevko small-block pans that use their pickup-mount main cap stud. I’m at the point in my 360 build where I need to pick a pan, and this one detail is throwing me off.
Kevko says the stud is an ARP part, but the number they reference (HARJ3.250-1) doesn’t appear anywhere in the ARP catalog. The only solid trace I’ve found is in a Summit Racing Q&A on the ARP 154-5201 Ford 351W main bolt kit, where a Summit tech said the individual pickup-stud bolt from that kit is ARP HARJ3-250-1.
So, potentially, this Kevko “Mopar” pickup stud is actually a Ford 351W main bolt with the threaded extension. Several other online retailers list HARJ3.250-1 as a “universal” stud, not Mopar-specific, which adds to the confusion.
Normally I wouldn’t care, but ARP’s own installation sheet for their main bolts says that switching from factory bolts to a high-strength fastener changes the clamping force and may require checking the main bores and possibly align-honing using the same hardware that’s going into the final assembly.
So now I’m looking at replacing one factory main bolt with an ARP Ford/universal stud… and mixing fasteners on a main cap doesn’t really sit right with me.
I’m not trying to stir up controversy or bash Kevko — their pans look great for the money. But on paper, this setup seems a little sketchy, and I’m trying to understand what I’d actually be bolting into my engine.
Questions for anyone who has actually run the Kevko pan:
For context: this is a street 360 with a stock-ish bottom end and factory main bolts. I just want a stock-ish pan with some baffling without creating a new problem.
I’ve reached out to Kevko and ARP directly for clarification. I’ll update the thread with whatever they tell me.
Thanks — just trying to avoid another rabbit hole on this build.

Questions for anyone who has actually run the Kevko pan:
- Did you use their stud as-is?
- When you torqued that ARP stud down, did the main cap pull, twist, or feel any different compared to the factory bolts?
- How did the crank feel afterward — any tight spots or drag during rotation?
- Any long-term issues like uneven bearing wear, oil pressure changes, or the pickup moving?
- Has anyone torn an engine down later and noticed anything strange with that main after using their stud?
