Well i ended up getting a screaming deal on a hotcam kit that im going to sell... I wanted to keep the rockers that came with it and i planned on running a 847 cam because i ended up getting a new one for 150.. anyway i noticed gm says these rockers are good for up to 575 lift???... im assuming i need to sell these as well since the 847 is somewhere near 590 with 1.6rr?.. anyone just confirm this for me thatd be great thanks

 

The rockers should be fine. Just check your valve spring/retainer clearance.

 

Great thanks. Just was a little curious.

 

I had those rockers on my xfi 280 before I switched and they needed to be clearanced about .020 to make fit or they would contact the retainer. That cam has 576 lift.

 

The GMPP rockers have a short slot hence the low lift capacity.
Buying everything on price gets expensive when the parts don't match and the results aren't what you wanted.

 

Thanks for the replies guys.
