Re: Help...1972 350 W/HEI

Check the easy things first.

Couple of things to look at.

When idling, check to see if you are getting at least 14.5 to 15 vds when measured across the battery posts using a volt meter.

Check fuel flow from fuel pump by remove inlet line to carb, place in plastic container and see if you get at least a pint of fuel in less than 30 seconds. If you don't, it could be bad fuel pump or restricted fuel lines.
