1406 Edelbrocks with the electric choke are my favorite carbs. Use them on performance built 318, stock 360 truck engines with the factory 340 cams, stock 67 383 10:1 compression 325 hp 4 bbl. They all run just great with the Edelbrocks on them. Easy to open up, clean out if you have dirty gas, and very easy to put kits in too. Simple low speed idle jets at the front base of the carb too.
