At the end of the day- if better torque is what yer after then an aftermarket piece is your best bet, this wide LSA's of the stockers don't allow for much overlap, especially with their short durations. Remember we're dealing with heavy trucks here, wasn't the LM7 cam ground on 114 LSA's rather than the 116 LSA as specified in the article..................

 

I'm not sure what exactly the specs were... i just assumed they had it right.

I agree the dyno seems a bit happy, but like any other dyno chart what matters is the relative difference. Thats where the real info lies.

I also totally agree about the stock cams and overlap. What makes low end TQ is late exhaust valve events and early intake valve events... that combo makes for much more overlap then they are willing to have in a factory cam.

 

I have an LS9 cam in my truck, with a Cloyes timing gear. After buying the cam, sensor, cover and springs I was in it for about $200.

I say if the LS3 and 6 cams are that close, pick up a cover, gear and sensor for ~$50-100 and install. There is nothing different about the swap except extending the wires, and reversing the 2 outside wires. Connector is even the same style.

 

I think we're getting to the point of questioning if this is a worthwhile endeavor....................

 

get a 2001 zo6 cam.

 

not worth it its dead. no GM cam is worth it. any cam were you loose bottom end and only gain 20hp top end in a truck it a waste of time and money
