My stock 78 carb even with just a mild cam (228/228) the idle circuit was way too lean so all 4 idle/down tubes will need to drilled out to idle decent on a 455 unless super mild cam. Pulls out of main circuit and gets "booster drizzle" to even try and idle. A 73 SD 455 carb right out of the box idles great!
