The 228R camshafts use lobes that are designed to be both beehive & double valve spring friendly.
The 228R 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. The 228R camshaft is a very popular camshaft for customers wanting a very streetable camshaft that makes approximately 5-7 more horsepower than the 224R camshaft. Dyno testing has shown the 228R camshaft to make a solid 45-50rwhp gains. The 228R camshaft is large enough that we recommend a larger than stock stall converter in automatic cars. Tuning will also be required in both automatic & manual applications.
