ARP Head Bolt Kit for AMC 343-401 1970-Up with Edelbrock Heads, 1/2 in. Chromoly, Black Oxide - 114-3604

If you're diving into a head swap or just need to tighten things up a bit, this ARP head bolt kit is a solid choice for your AMC engine. Designed specifically for the AMC 343 and 401 models from 1970 onward that are rocking Edelbrock heads, these bolts are built to handle the heat and pressure that comes with performance engines.

Now, let’s talk specs. These bolts are made from tough chromoly steel, which means they’re not just strong; they’re also lightweight. The black oxide finish gives them a sleek look while providing some corrosion resistance—definitely a plus if you’re working in less-than-ideal conditions. The hex head style makes installation straightforward, and you won’t need any special tools to get the job done.

Each bolt is threaded at 1/2 inch, which is standard for these applications, and they come with washers included—no need to hunt down extra parts. Keep in mind, these aren’t cut to fit; they’re designed for a direct fit, so you can trust that they’ll work seamlessly with your setup. Just make sure you’ve got the right heads, and you’re good to go.

Overall, if you're looking for reliable head bolts that won't let you down when it counts, this ARP kit is worth considering. It's a straightforward solution for anyone who's serious about their AMC engine build.

The Story Behind ARP Bolts

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.
