harmonic balencer???

[5literstang]

ok i have some kind of vibration with my car when it goes over a 3500 rpms, if it's in 1st gear it pops out and in any other gear it seems to vibrate or have a griding noise coming from the shifter, i know it's not my trans cuz that was just rebuilt. and it started doin it after i got it back from the shop when i got my new motor put in. the mechanic told me it had something to do with the harmonic balencer, i dont want to take it back to the shop cuz i had problems with them and i dont trust them after i filed a complaint against them. so if u guys can help i would appricate it, right now my dad has the car and he was telling me about and i decided to post about it to find out the problem, thanks -Jeff

Get under the car and look at the balancer. If there is rubber coming out of it it's done and time for a new one.

the mechanic that did my car told me about the viberation and he said it might need to be rebalanced or something, where is it located and if i need a new one how much will it be? thanks

It's on the crank behind the crank pulley ( I don't have a pic sorry) It's that last bottom pulley near the oil pan.

Your "new motor" was built with a 50oz balance bottom end? Or 28oz? You need a balancer that matches, if thats the problem, make sure you get the right one, your flywheel also must match the balance of the crank. Also, did you index the bellhousing to the new motor? Just some thoughts...
