[bigfoot]

what are the simptoms of a bad one?



im getting intermittent bogging when i accelerate.

the float levels are ok, havent looked at the spark plugs yet.

its a 4160.

A power valve will make it bog. There cheap to change. If it still does it, check your fuel pressure, mine developes a bog when the pressure is to low. http://www.s10v8.com/images/smilies/icon_wink.gif

Holley Power Valves are so easy to blow. I had a Holley in a 79 El Camino with a built 350 in it a long time ago, and it did absolutely nothing except give me problems and more problems. Quadrajets and Edelbrocks are the way to go.
