Having a custom-diameter LS piston made isn’t a huge undertaking these days, and we’d need a custom piston anyway to bring the LY2’s OEM compression up from its meager 9.1:1 factory compression ratio for this comparison.For the cylinder heads, there’s really not much imagining that needs to be done, as the LY2 comes with the cathedral-port 799 head, which offers decent flow from the factory. With their 209cc intake ports and 74cc exhaust ports, and a chamber diameter designed to work with the 3.78-inch bore engines, the 3.858-inch bore of our hypothetical engine will work well with the 799 heads.Since this hypothetical test is meant to fall on the more factory side of things with unported OEM castings for both engines, and the 799 castings are generally accepted as the best factory option for the under-4.00-inch bore size, we don’t feel like we are putting the LS engine at any disadvantage. On the flip side, as they are the original head found on the LY2, which is a Gen IV LS design, it’s only fair that we use them when comparing to second-generation Coyote head–so no, we aren’t giving the LS an unfair advantage, either. We were able to locate flowbench data for the 799 cylinder head, so coupled with that data, and the 2.00-inch intake and 1.575-inch exhaust valve sizes, the program has quite an accurate representation of the LY2 head.For the Combustion section, we went with a piston with a 12cc dome, which, when coupled with the 799 heads’ 64cc combustion chamber and a.041 compressed-thickness and 4.100-inch bore head gasket, give the combination an 11.28:1 compression ratio.

Coming from the factory with a 3.780-inch bore and 3.267-inch stroke, a simple.078-inch overbore would bring the engine’s displacement to 305.5 cubic-inches or 5.006 liters of displacement.While that might sound like a fairly large overbore, there are quite a few instances of the 4.8-liter blocks being bored to the factory LS1 bore size of 99mm or 3.898 inches and living.
