Ls3 Head Upgrade at leonargroomso blog

Ls3 Head Upgrade. the ls3 head upgrade also requires the corresponding offset (intake) rockers and intake manifold, but the stock ls3 heads offer an additional 70 cfm per runner. Reaching the 500 horsepower mark with an ls3 is really representative of the “real world” scenario for most hobbyists.

Tested on a 408 stro­ker, the ls3 head upgrade was worth almost 40 hp over the stock 317 truck heads. In addition, we also have a specific supercharger guide , camshaft upgrade guide , intake manifold upgrade guide , and a throttle body upgrade guide. These heads are almost the same, but the l99 heads.
