I've gone to EFI and no longer need this. This is a nice and clean setup...just pulled it off my '56 Belair not 3 weeks ago. 750 CFM Speed Demon Vacuum Secondary carb with a black anodized aluminum Mallory fuel log/regulator and fuel pressure gauge for sale. Will come with assorted small parts (vac secondary springs, needles/seats, vac sec diaphram, power valve). Has re-useable fuel bowl gaskets. Mallory fuel log is capped off, but can be used as an adjustable regulator with return line. Has -6 AN adapter for fuel inlet. I don't think Mallory makes these anymore. Is Mallory part number 4304M. http://paceperformance.com/i-6114348...log-4304m.html $450 plus shipping for carb, parts, and fuel log/regulator.
