Brenspeed B326 Key Ingredients
Boss 5.0L Modular Block
The Boss 5.0L Block is cast in Fordís Cleveland plant and shipped to Brenspeed for final prep. Ford designed this block with a proprietary iron mix to yield the strongest possible casting strength yet greatest consistency possible. The freshly cast block is prepped, machined, and quality checked to assure each and every block meets our specifications.
Kellogg 3.800 Stroke Forged Steel Crankshaft
Kellogg crankshafts are made in the USA and machined in Jackson, Michigan. They feature oil holes that intersect shallow oil hole pockets in the main bearings to help maximize bearing surface on the mains and improve oil flow to the rods. Fillet rolled to increase strength & OD induction hardened to provide maximum wear resistance. Two step polishing process for the rod and main journal surfaces. Beware of imported crankshafts that offer a low price but are not made in the USA! Kellogg crankshafts has been family owned and operated since 1956!
ARP Main Cap Studs
ARP is yet another company that proudly makes their products in the USA. The ARP main studs used in the B326 are manufactured from 8740 chrome moly steel, heat treated to 200,000 psi tensile strength, and precision j-form threads rolled after the heat treating to create a fastener that has threads 1000% stronger than others. What does all that engineering talk mean? It means your B326 crankshaft is secured in place with the best fastener on the market!
Manley 4.6L Stroker Connecting Rods & ARP Rod Bolts
Manley manufacturers these connecting rods from 4340 forgings. They are Heat treated, stress relieved, shot peened, and 100% magnafluxed. We have used thousands of Manley connecting rods over the years without failure and is our choice of connecting rod in the B326 stroker!
CP Pistons & Ring Set
CP designed our B326 pistons (9:8:1 compression) with 5 things in mind. Tighter clearances, less noise, better ring seal, more power, and more durability than other brand pistons on the market. The forgings were designed using advanced 3D modeling which allows CP to check thicknesses and weights before machining enabling them to produce the strongest yet lightest piston possible. Once designed they are machined on a 5-axis CNC machine while computerized electronic inspection equipment confirms they are manufactured to the tightest tolerances in the industry.
Complete Clevite Rod Bearing Set
Our B326 feature the Clevite 77 TriArmor rod bearings. These bearings feature a sophisticated blend of materials that offer extraordinary protection and lubricity. The enhanced wear characteristic of TriArmor bearings increase bearing life in race and high performance street engines. Combine that with Clevite TriMetal technology and you have a bearing that has great protection during start up, reduced friction and drag, ability to withstand extreme temperature and pressure, and extraordinary strength and durability.
Complete Federal Mogul Speed Pro Main Bearing Set
Our Speed Pro Main Bearing kit uses materials and alloys engineered for the demanding applications your B326 may be put through. Speed Pro has tailored their bearings to withstand punishing racing conditions. They are proven winners in NHRA, NMCA, NMRA, Nascar, and IHRA.
