Any suggestions are appreciated. I have an Edelbrock 1405 Performer, bought the rebuild kit, high altitude jets and metering rods and the off road kit. Just wondering if anyone has any pointers, heads-up etc on this process. I've never rebuilt a carb but it doesn't look too hard. Also wondering if anyone has installed this off-road kit on a Performer and what results they had. (hgh altitude tips would be great) While I'm at it I'm thinking about putting a better intake manifold in (maybe a Performer also?) any suggestions on that would be appreciated too. Oh, this is in a '72 K5 with 350/350.
