well i got my ole q-jet out it took a poop on me and wasnt running right. so i got a used holley 4160 and slapped that on there. just got it tuned to were i want it i think but when i go into drive i stillhere this rattling sound sounds like its coming from the trans area. i got the trans kickdown cable attached and im sure i have all the vac hoses in the right spot any idea what else i can do this is an 87 trans am lg4 and the holley was rebuilt

 

What dististributor are you using?

 

stock dist. i have three vac lines that i have to hook up. one is on the base of the carb i beleive its for the vac advance on the dist. the other is a brass fitting on the main bowl assembly that i think goes down to the trans vac line. and the third i have plugged and its right under the secondary diagphram

 

A stock distributor doesn't have vacuum advance, unless this is a Canadian car.

 

ok i learned something new today thanks. so does it matter were the vac lines are hooked up to or just hook them up. i know one goes down to the trans and the other looks like it goes down to a sensor by the dist from there i cant see. on the holley and its an older model theres the brake booster line which is hooked up. then on the passenger front on the bottom is a connection for line there. then the brass fitting on the main bowl assembly and one by the vac secondary diagphram the carb is a 4160 model if that helps

 

You need a different distributor. One with vacuum and mechanical advance. The stock distributor is operating in "limp home mode".

You also need a geometry corrector bracket for the transmission throttle valve cable - it isn't a "kick down" cable, and unless you get this right, you will burn out your transmission.

 

rodger that thanks for the info. guess that hour drive i took yesterday to go on a date wasnt such a good idea eh. oops live and learn. though it does seem fine when im driving but not so fine when im in gear and idling. can you give me some part numbers for those items you told me about

 

would the canadian model dist work for my car with the holley 4160

 

If it was from a non-computer control LG4, yes.
