i have heard of putting in a 4 degree advance cam key in the 2.8 litre engine with good results, has anyone done this? how much gain could i expect (it's a 2.8 i need all i can get)?:bah:

You would be a lot better off with an aftermarket cam. I don't know what 4 degrees advance on the stock cam would do for you, but the stock cam specs still aren't all that impressive to start with.

I know nothing about these things but I have just acquired an 85 s-10 extended cab 4X4 that has no power. I went to a highly recommended muffler shop and they told me that a higher performance exhaust system would not materially help and had no real good thoughts other than a hotter spark plug. I am looking at any reasonable way to get more power.
