Here's a real world example of a N/A 302ci stroker build in a 2009 GT:
302ci Stroker & HCI
Combining a 3.800" stroker crankshaft with the 3.554" cylinder bore of an honed 3V block increases displacement from the stock 281ci (4601cc) to 302ci (4942cc). The compression ratio is also increased from 9.8:1 to 10.5:1 when using flat top pistons with 6.25cc valve reliefs. This stroker combination was dressed with Livernois stage 3 ported heads, XFI 127600 SPR camshafts, Livernois cam phaser limiters, FRPP intake manifold, FRPP dual 62mm throttle body, FRPP 39lb injectors, SPEC 12lb aluminum flywheel, and a
Shaftmaster aluminum driveshaft.
