Is the ARP bolt the one that will actually install the pulley AND be reusable?

Or would you still have to use that tool or longer bolt to pull it back on?

I love my powerbond because it has the high ribs to help in not letting the belts slide off.
Also I would recommend the melling oil pump it comes with the high pressure spring installed and a low pressure in the box. I left the high pressure and love it.
Also I would highly recommend the LS2 timing chain, they are like 35-40 bux and you can reuse your sprockets if they are still ok.
Who is going to install the cam?

Thanks

if you run a double roller timing chain some of the pulleys wont work without being machined a lil...also some people have said that your voltage from the alternator may drop some due to it being turned slower but you can buy a alternator pulley to offset that.

**** dude, get the word out

dont remember, do you have a LS6 intake? im thinking 380-390ish. with 5 million ftlbs of torque
j/k torque should be about the same as hp numbers. i think i had 10 ftlbs more than hp with the 224 cam. or maybe it was 10 less
