1.7 roller rockers, if memory serves right the stock 2000+ 5.3 cam is a split pattern around high 18x duration w/.48x lift on a 114lsa. Most 2000's I have seen dyno around 230-240hp stock.

Re: Engine paramaters

we do not have roller rockers, we do have roller lifters, but the rockers are solid machined steel(?) roller rockers are available from jesel and a few other vendors.
