>Yep replaced the filter first thing. Isn't there a screen at the tank also? >Johan Where was the filter that you replaced? My big block experience is not with Imperials or '65s, but if I remember there is a teeny tiny filter at the carb inlet and the sock filter over the pickup in the tank. I ended up adding a glass filter (oh be quiet, it's only temporary) in the line between the pump and carb. It fills up with sediment so fast that I knew I needed a new tank.
