vibrations

alright, i have a nice little vibration from idle up to about 2500. havent driven it, this in park, when i put it in gear, it shakes like a mug. im pretty sure i now know what it is, i searched and got the answer, i just want to see if you guys think this could be my problem. so anyways, go to drop the motor in the other night, had to put a new flexplate on it, i got the correct imbalance. so i dont have the torque specs, i call my builder, its after hours and one of his workers answers. its like some 18yr old kid..(Not knocking young kids). i say hey lemme speak to james, he says hes under a truck working on a clutch. i say ok, you should know this...what are TQ specs on driveplate bolts for a 302 and do i used a threadlocker. he says no threadlocker is needed and i should tighten to about 56ftlbs.

so i totally feel like a dumbass for not rechecking and just taking his word...i mean ive never done something like that before. ive done heads and intake and that stuff, but never a flexplate or flywheel or anything of such. so after searching ive found that they should be about 75-80ftlbs and more than likely im leaking oil since i didnt use the locker.

so my 2 questions now are, do you think this is what my vibration is? and what color locker...red or blue?

yeah that was the first thing i looked at, usually if i have a dead hole you can tell by the exhaust. but it sounds the same as always. ive checked all the plugs, wires, the injectors. ive got plenty of spark. i just have this bad feeling is gonna be those bolts, seeing that i stopped about 20lbs shy of where they are supposed to be.
