Rockers will add power. Hook up with some of our other NE members for a mod day, and you can all do the upgrades together.

Which cam, what other mods, and at what RPM'*?

A came can add anywhere from 5-15 hp depending on what you get, but you have to decide WHERE you want the power. I'm putting a cam in this fall for more mid-high range power. I don't need any more low end, and don't want to kill my trans again. Compared to the S2, I fall on my face at the 1/8, and they run me down.

Your situation will be different. I suggest starting with the cam manufacturers, and go with their reccommendations. Or start with a member that'* done it, and model their setup.

Nah, my question was how much the rockers / springs / pushrods will add. I don't want to put a cam in becasue I plan on selling this car next summer and buying a Mustang 5.0 , but I want to have some fun with the Bonneville till then.

Rocker will add maybe around 10-15hp extra in the higher RPM range, and I believe thats to the wheels, unlike the intake and exhaust..

Ehh, if your gonna sell it, just skip modding it for now.

I'm going to try to keep it, I've just wante da 5.0 for two years now. It all depends on how much I can save up.

Plus, my dad loves my bonneville and wants to buy it from me, which would be nice, and I could still drive it.

Rockers will also increase the gas mileage of the car on the freeway. They increase the lift of the camshaft already in your motor.

Technically it increases the valve lift over what the stock cam gives you.
