No, the Detroit Pistons haven’t moved to Cleveland; although, if that move would reward the Pistons with Lebron James, they would be there in a second, and they’re championship ways would return. However, that’s not going to happen, and who knows where King James will end up. One thing’s for sure, the Pistons should’ve never let loose of Chauncey Billups. What were they thinking? After season’s end, Rip Hamilton will be gone, too. Anyway, thinking of building a 351 Cleveland, Diamond has a set of pistons for you after the jump… Clinton Township, MI: Diamond has just announced a new series of dished stroker pistons to suit all factory-style Ford Cleveland cylinder heads (2-valve and configured for two- or four-barrel carburetors). These include aftermarket variants: AFD, CHI, Blue Thunder 3.6, Edelbrock Performer RPM, and of course the Ford C302B—the Cleveland Boss head adapted for use on the Windsor block. Strokes and Bores
Devised for aftermarket crankshafts, these dished stroker pistons provide stroke lengths of 3.750, 3.850, and 4.000 inch. The stroke lengths are attained by using either the Ford OEM connecting rod (5.596 inches with a .912 inch wrist pin) or by the Chevy 6.000-inch connecting rod with a .927 wrist pin. Bore sizes begin at 4.000 inches (standard bore) and extend in small increments to 4.060-inches. Compression Capabilities
Developed for use with pump fuel and with compression ratios of around 9.5:1 to 10.5:1, these pistons are recognized by their dished configuration, which, for combustion efficiencies, mirror the outline of the Cleveland’s combustion chamber. Though unsuitable for high boost or high nitrous pressures, they have sufficient wall and crown thickness to accept 10 lb of boost or 150-200 horsepower shots of nitrous. Therefore they are ideally suited for the weekend warriors and the budget bracket racers, for older Mustang and Torino restoration projects, and for street rod builders. Rings and Rails
The Diamond stroker Cleveland dished series pistons are supplied with a conventional ring stack: 1/16-inch (top ring), 1/16-inch (second ring), and 3/16-inch (oil-control ring). On the longer stroke models where the top of the wrist pin bore intersects the oil control ring groove, oil ring support rails are provided. To prevent the support rails from rotating in the oil ring grooves, they are fitted with the dimple pointing downward and located in the gap created by the wrist pin bore (see accompanying image). Pins and Locks
Also included in these Diamond stroker kits are wrist pins (available in uncoated H13 Tool Steel, as shown, or coated in the desirable DLC Casidiam) and spiral locks (available with either single or double spirals).To lubricate the wrist pin, these pistons feature double oiling ports in each wrist pin bore, which are fed from the oil control ring groove. Diamond dished stroker pistons for the 351 Cleveland are available in 5-7 working days. For further information contact:
