600 Edelbrock on a little guy
I've got a stock 1985 305HO with an Edelbrock 600 (#1405) carbeurator. I've gotne through it with a grinder and file to try improving flow to get a better booster signal. It has mechanical secondaries. The only thing I've done to the engine is remove all of the emissions bs and rebuild the ignition with a vacuum/mechanical advance HEI unit. I also went with new plugs, wires, a 160 thermostat, and tuned everything based on manifold vacuum readings. My problem is that the carb is technically too big. I've got flat spots in the power curve that I'm just chasing around with jets and metering rods. I know that a 305 is just that...but i'd like to believe that I can get some pretty good performance out of it with a 373 gear. It's very drivable, but just not what I'm used to in terms of response and or transitions. If anyone out there has figured out a better way to set the mechanical secondaries, or has a combination of rods and jets that they're happy with, please let me know. I'm just not used to little motors. I can't make it happy for some reason. That, and I don't really care for Edelbrock carbs.
