The 224/228 camshafts use lobes that are designed to be both beehive & double valve spring friendly.
The 224/228 camshaft is available in a wide variety of lobe separations. The most popular options customers select is either the 112LSA or the wider 114LSA. The 112LSA helps to bring the camshafts powerband lower in the rpm band. The lower LSA also creates a slightly rougher idle. Boost applications typically stay at 114LSA or wider with this camshaft.
