I'll change it to a steel one, what would be a good one? How about the fact it'll run for about 10 minutes or a little more then hit traffic or many traffic lights and I could feel it coming on, she'll idle rough and then stall? The temp was one issue, it's improved a lot, now I rebuilt the 600 Edelbrock with new rods, jets, floats, idle mixture screws and it still runs like SH#&, I threw a Carter AFB(clone)9635SA together and seems to idle, great, runs sweet, but it seems like I'm not getting enough fuel after she runs for awhile, the engine stumbles and idles like it's starving, and when I try to take off it'll stall. It was suggested to install a fuel filter before the pump, is this a good idea? My fuel pump is an Ames perf. special Mr. Gasket High volume.
