I sprung a leak in my front engine cover in gasket were water pump ports are. So I figured since i'm going to be so close to my timing chain I'm going to change my chain and gears. I bought a Cloyes timing chain and gear set, now that I got it and I'm looking and reading the directions the cam gear has 3 marks for timing. 1 for stock cam timing another for advanced cam timing for to increase bottom end HP and 1 mark to retard the cam timing to increase the topend HP. My questions is I would like to advance my cam timing to get the bottom end gain, but I'm running all stock engine componts. Does anybody forsee any problems with doing this? Thanks guys
