305 SBC vs 302 SBF: Does Compression Help the Lowly 305 beat the Race-Bred 302?

It’s Round 3 of our 305 Chevy vs 302 Ford Small Displacement Showdown, and we are making one HUGE change in compression on both engines, then putting them back on the engine dyno to duke it out! The only parts we are altering are the pistons, swapping each for a set with a big effective dome, and we go through the whole process of honing the blocks, balancing the cranks, and reassembling our 5.0L powerplants. On the dyno we show you how much compression adds for power on each and see how the Blue Oval and Bowie stack up with a lot more squeeze!!
