[IAFF2407]

worked flawlessly. The gas mileage dropped though. I had the 750 Quadra jet before, which has small primaries, size of a quarter, lol. its the secondary's they're so big you could stick your hand through. ( exaggeration )
turn key with the Holly, engine turns over 7 times and starts. cold starting, same, idles to about 1500, then down to 750 after 30 seconds, every time. tunes up with a computer. I had Pertronics make me a elc. distributor. shaft is from a caddy the rest is from a "86 (?) corvette. | haven't installed it yet, will be using a wide band O2 sensor so the complete tune up will be from a computer.
