Destroked Small Block?
I just delivered a small block 2.96" stroke billet crankshaft to my machine shop that was custom made for me by Bryant Racing in Anaheim, CA. This 305 will be the "street" motor for my '72 BBody project car.
i will be using factory correct '72 Thermoquad and '72 cast iron intake manifold. An almost copy of the 1968 factory spec 340 (manual) hydraulic camshaft, custom rods (longer than stock), and factory 340 open chamber cylinder heads (2.02 intake valve). The old school 12:5 to 1 domed TRW (L2322F) forged pistons will only provide about a 10:5 to 1 compression ratio due to the loss in compression inevitable when de-stroking. I hope horsepower will equal the factory 340, obviously torque will be at a loss.
340 @ 5000 rpm = 492 CFM
305 @ 5600 rpm = 494 CFM
