Hawks Motorsports is pleased to offer our clients the following 134-2001 Small Block Chevy Hex Head Chromoly Intake Manifold Bolt Kit, 3/8"-16, 1" UHL, Set of 12, ARP. Designed for Chevrolet Small Block 265-400 CID engines using a factory OEM-style intake manifold, this ARP kit includes 12 black oxide chromoly hex-head bolts and washers. The bolts feature a 3/8"-16 thread and 1.000-inch underhead length.

For the gearhead who has spent time cleaning up an old Small Block Chevy and putting the engine back together the right way, hardware matters. There's nothing quite like opening up a fresh set of ARP fasteners when you're finishing an intake install on a 283, 327, 350, or 400 SBC. The black oxide finish and hex heads give the engine a clean, purposeful look while replacing a mismatched collection of old bolts with properly specified hardware.

ARP's 134-2001 is intended for factory OEM-style Small Block Chevy intake manifolds. The bolts use a 3/8"-16 thread, 1.000-inch underhead length, hex head, black oxide finish, and chromoly construction. The kit includes the complete set of 12 bolts and washers required for one intake installation.

This kit is specifically different from ARP's 134-2002 application, which is intended for 305-350 Vortec engines and most aftermarket aluminum intake manifolds. Verify the intake manifold and engine configuration before ordering to ensure the correct fastener length and application.
