TSP Naturally Aspirated Camshafts, LS1/LS2 Applications

TSP 220R- The 220R camshafts use lobes that are designed to be both beehive & double valve spring friendly. This is an excellent performance camshaft with a smooth idle in 346cid and larger motors!  We've had tons of customers select this camshaft when looking for a cam that drives almost stock and can be practically hidden with some exhaust systems!  If you’re looking for a small stealth camshaft the 220R is a great option to consider. The idle is much more aggressive in 4.8/5.3 applications but still retains great street manners.  This camshaft is a great choice for daily driven LSx Trucks wanting a lopey idle.  It even works with stock torque converters.

TSP 224R- The Stage 1 camshafts use lobes that are designed to be both beehive & double valve spring friendly. The 112LSA helps to bring the camshafts powerband lower in the rpm band. The lower LSA also creates a slightly rougher idle. The Stage 1 camshaft is without a doubt one of the most popular camshafts we offer for the LS1 engines. It has awesome drivability while making a solid 40+ rear wheel horsepower gains!  For customers looking for a smaller camshaft that packs a big punch, the Stage 1 camshaft is pretty hard to beat!
