That much cam in a 350 engine will require custom tuning.  It needs a lot of idle fuel and idle bypass air.

From what I've seen, the JET builds are "generic", and attempts to get them to custom tune usually end up with the same results that you are seeing.....Cliff

so whats my next step ? i picked up your book and am reading it. theres a guy here(in monroe,wa) that says he can tune it but wants it for a week(the whole car) and wants a min of 350 bucks almost as much as i payed for the carb. im running out of money ....george.... carb #17059203-2278ccb

here is where you get real familiar with how the q-jet works then tear it down and find out exactly whats in it and how its setup book shows you everything to them. then post it all on here and then cliff and everyone else can help you dial it in. only way to be able to point you in a direction wish there was a different way

Needs it for a week?  Should be able to dial the carb in for what you are doing in an hour or so.....Cliff
