Brian Tooley Racing CAMSHAFT – N/A 400CI+ NA version 2

236/25X, .644″/.644″, 114 LSA

Developed in-house using BTR designed lobes, the new Stage 400″ NA cam is the latest offering in the BTR Stroker line up. The all new BTR 400″ NA camshaft is a great all around camshaft for use in 402-427 cubic inch engines in the 3500-7000 rpm range. With 18.5 degrees of overlap, it has an aggressive sound, but is docile enough to be driven long distance if needed. The updated cam timing events work well with either Square or Cathedral Port heads along with both long runner FAST or Victor Jr style intake manifolds.  This camshaft may also be used with a Centrifugal style blower like a YSi, F1R, or F1X as well as with 250-300 hp worth of nitrous.  Many people think that increased exhaust duration kills mid range torque, but in back-to-back testing we’ve seen more power from 3500 RPM to redline compared to cams with less exhaust duration. These new BTR lobe designs were Spintron tested to help  maintain strict valve train stability and durability standards.

Brian Tooley Racing (BTR) – the story

Brian Tooley has been in the performance racing game for nearly three decades.

Starting his own business back in 1992 called Total Engine Flow, Brian was using a Flowdata flow bench. Shifting to Holley Performance Products shortly afterwards, he helped develop the SysteMax head, intake and camshaft packages.

Going back to working on his own in 1996 until 2004, Tooley then built Total Engine Airflow into an industry titan.

Since then he sold his business to Summit Racing Equipment and stayed on until 2010 when he decided to be closer to family and friends.

As his BTR webpage revealed, it wasn’t long before Brian was back after seeing a need for quality spring kits at affordable prices.
