My engine now has over 100K miles on it and still the same timing chain I'm doing my cam swap, so I'm going to also do my chain, which one should I go with? i'm Running a Vortech 9lb kit, with long tubes, 220/226 .564/.569 -114+4 918 springs and titanium retainers.

Being a 98 I would go ahead and throw on a new one. If you have the money to do everything else... buying a little insurrance never hurts.

While your doing the timing chain you should do a ls6 ported oil pump too, you can pick one up for approx $140

I just installed a Rollermaster double roller chain/ported LS6 oil pump in mine both went on pretty easy but I did have to machine my old ASP pulley for clearance.

I used the GM heavy duty chain and dampner which will bolt right into a 98 block.

wonder if I would have to machine my Vortech Crank Pulley if I did the LS6 ported oil pump
