MAKE IT BIGGER
Some engines are harder to increase the compression ratio on than others. Sometimes we are limited in cylinder head chamber size and sometimes higher compression pistons are not available or effective for certain engines. Increasing the crankshaft stroke is an often overlooked but very effective way to increase the compression ratio and you get a bonus, a displacement increase.
