The ISB build always begins with TCB's "Matched Induction" components. 54mm cam tunnel boring plates in action. Roller bearings will allow higher RPM, increased oil pressure to the mains, and the ability to run larger springs and seat pressure. Add a fully ported, big valve cylinder head with high flowing aftermarket intake manifold and let the "smoke roll"!!
Cylinder head improvements start with the valve bowl and include larger seats, filled with .125 diameter larger intake valves. Check out the "stock" valve with the dimple in the center as compared to the larger replacement. TCB exclusive seat profile along with "matched" camshaft and intake porting round out the package! More to come!
