Hey guys looking to upgrade the .... um..... cough cough 289 that’s in my 64 merc ( it’s a 70 302 all stock) anyways it’s a cast iron intake 2 barel carb right now. I bought an aluminum ford 4 barrel intake Shorty headers A set of aluminum valve covers And the 84-85 duel snorkel air filter assembly used on the mustang. Bought all this stuff used for pennies on the dollar. I got about $250 invested so far ! anyways I’m looking for a carb and there are quite a few edelbrock 1406 and 1405 carbs 600 CFM The 1406 is electric choke and 1405 is manual choke. what I’ve read it’s a great reliable carb for the 289. I have never futzed with an edelbrock carb how are they ? Bolt on tune and go or are they a constant diddle carb. I know carbs and am familiar with them but other then my o/t air cooled vw’s I’ve always just rebuilt the stock carbs and bolted them back on. anyways any real world experience with these carbs? And any other tips or tricks to wake up this 289? just to add I’m looking at used carbs and they are selling in the 200-350 range depending on age, but all are clean and work. So a kit and go ?
