stuttering problem with carb..need help

i have an 86 camaro with a newly swapped in 350 crate motor. my engine has been stumbling for a while, the dealer recommended doing a complete carb overhaul, among other things. my dad thought it would be relatively simple to get rid of the qjet for a holley or something. i passes smog in early in the year so i wont have to pass again for about another 18 months. my question here is this:should i go ahead and get the carb rebuilt(i tried once with my dad, we replaced the gaskets and stuff but it didnt solve the problem) or should i replace the carb with something that is non-computer controlled?

and if i do switch to non-comp controlled, what else do i have to switch too, to allow it to run good?

also, what are the going rates to have a 86 q-jet carb completely rebuilt?

i also heard of some G hangers or H hangers, or something like that, that may help performance?

thanks

daniel

If you go w/a NON cc-carb. then you will have to get a non cc-distributor w/vacuum advance. If not this could damage the motor. But keep in mind if you do this, then your ECM will no longer be hooked up. Just something to think about.

so far i havent done anything. the ecm is still connected and functional. how much would a distributor like the one you are talking about(vacuum advance?) cost?

thanks for the help

You'll also need to rig the tranny to make the torque converter lock up at the right time. There is a kit from B&M or some place like that that'll take care of it for you. I think you'll also have to rig the fan, or fans, to turn on at the right temps. Or maybe not, can't remember if the computer tells the fans to turn on or not on LG4's or not, someone else will surely know.

You need to replace all the diaphrams in the carb. They have probably hardened.

I got my distributor from a local speed shop, it is an Accel HEI and cost me $160, but that doesn't come w/ a ignition coil.
