The block is bored 0.30 over and I'm using a hotter cam (216 intake/224 exhaust @ 0.05, 0.506 lift) and will be running the usual bolt-ons (4-bbl and appropriate intake, headers). My horsepower goal is 300+ My question is this - I found a set of Harland-Sharp roller rockers that are a bolt-on replacement for the stock rollers - are they worth the expense? Any info would be appreciated.

If your originals have a ton of miles I would replace them with OEM or Hughes engines (they advertise here) has a good replacement set...just don't believe the EXTRA expense of the H/S rocker would help you. Spend the money on: port / bowl blend work / quality valve job...there you will see improvement my

You did not mention it or not- The HS rockers come in two ratios (stock 1.6 or 1.7) I used the 1.7's on my 2000 Durango and it made more power upstairs around 4500+ rpm. Only other mods was a muffler and bored throttle body.
