Thread: stock cam and 105lbs springs

You won't have any problems. You may want to upgrade to a double roller timing chain though.

You don't need a double roller for 105's and rockers... Before my cam swap, I ran 105's with 1.9 rockers on my original timing chain/dampener for 30k miles with no problems. My cam swap was done at 105k miles, in which a new stock chain and dampener were installed. The factory chain/dampener appeared to be in excellent shape upon removal.

OP: Your stock cam will be more than fine...
