If you’re diving into a Buick 350 build, you know the importance of solid fasteners. I’ve been around the block with ARP products since they first hit the scene back in 1968, and let me tell you, they’ve come a long way. These guys really know how to blend technology with race-proven designs, and their fasteners are no exception.
Take the ARP 120-3201 Timing Cover and Water Pump Bolt Kit for instance. This isn’t just any bolt kit; it’s designed to handle some serious stress. We're talking about head studs and bolts that can withstand extreme loads, which is crucial when you’re pushing your engine to its limits. The installation pre-loads are impressive—these fasteners get stretched to the max during installation, ensuring a tight fit that keeps everything secure under pressure.
Now, let’s get into the nitty-gritty. This kit comes with a selection of socket sizes: 5/16 12pt, 3/8 12pt, and 7/16 12pt. That’s a good range to cover various needs, whether you’re working on the timing cover or securing the water pump. The 12-point design is especially handy because it gives you better grip and reduces the chance of rounding off those edges when you’re cranking them down.
Honestly, if you’re serious about your build and want to avoid the headaches that come with inferior fasteners, this ARP kit is worth every penny. I’ve seen too many projects go sideways because someone skimped on the basics. Don’t let that be you. Go with ARP and rest easy knowing your Buick 350 is held together with the best.

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless.
Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.
What Makes ARP Bolts So Special?Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes.
ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.
ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
