Great camshaft for LS1/LS2 applications where a really rough idle is desired with more top end power than the stage 3 cam, will need a stall converter!
This camshaft is very aggressive for a daily driver application. With 16 degrees of overlap it has an aggressive idle, and makes great top end power at the sacrifice of some low end torque. The increased exhaust duration will pull very well in the upper RPM's without power falling off like other cams might. Cam specs are 233/248 .630"/.615" 111.5+2.5 and comes a 3 bolt timing gear pattern.
