Installation kit and timing chain $157.29
Amsoil 20w-50 racing oil + filter $40
Total $524.21for 30 horsepower sounds good to me
Got a link to that cam? I'm curious what the specs are. You will likely need valve springs if you want to rev much over 5500 anyways, stock valvesprings suck pretty bad.
Also, I definately don't think I'd run 20w-50 at all. Way too thick for these engines. Its not a small block......
10w-30 AT MOST. Most of the people making good power run 5w-30 or thinner. I run 5w-30 in my 99 GT and have for the last 20k miles. The bottom end has a little over 220,000 miles on it and makes over twice the power it did stock and I've had 0 issues, when I had the heads off the original cross hatch was still very visible on the cylinders.
