OP, the Edelbrock carb with electric choke and mechanical secondaries is the 1403 but 500 CFM. You can download the owners manual which shows all the adjustments. Its basically like a Carter AFB carb. Not as fussy to tune as a Holly

I have used the 1406 on both Chevy and Ford small blocks. For me its a simple, reliabl and easily tuned. Vac gauge, timing light and tach are your friends

I also have a FP gauge on my 357 (67 Camaro) with a 1496. The AN Edelbrock carb fuel line, filter, SS fuel line with a FP gauge on a 6AN to 1/8 NPT T
