Idle Speed on a 83 Jimmy w/ 350?

[beefcake83]

Hi all - Is there anyone who knows what the idle speed should be for a '83 Jimmy with a carbed 350 (Rochester)? I'd go by the sticker on the radiator support, but the original 305 was pulled, for the 350 that is there now. Thanks

Should be the same as your old 305, about 500 RPM in drive. I think the fast idle is in park (not sure) but thats 1,600 RPM.

After consulting my Haynes, I'll second what Blazer Boy says. Set it for 500-700 RPM, and you'll be golden.
