Was this a new carb? Idle at this time is not a prerequisite, flatout and finding weak links is the goal.moparman said:made good power, hard to tune, part throttle and idle tuning is almost nonexistant, at least on the one I worked with.
I think it was converted to street version. From seeing other's posts on here, I think most of the problem was the motor itself. It was a 440 ci lucky to be 8:1 compression, stock valve, ported smog heads with a [email protected] .470" lift and 108 LS. Dual plane action plus manifold. Like previously mentioned, the throttle response was great. I'd be interested to see what the carb would do on a larger motor with compression and good heads.Brad Johnson said:
