Default RE: can't figure out this VIBRATION

I know this is gonna sound crazy, but since this post, I put in a new 306 short block, cam, lifters, pushrods, used the same heads, new harmonic balancer, new injectors, new tranny mount, had the transmission rebuilt, new pilot bearing, put back the new flywheel and clutch assembly and figured I'd be good to go. I started the new engine for the first time and IT STILL HAS THE SAME FREAKIN VIBRATION!! I cant even belive it. How is this possible? I can't even describe how PISSED I am.
Any Ideas?

ORIGINAL: 90mustang5.0

why was it converted back to a 5 spd, shoulda kept the auto in there they don't break as easy once u have mods in your car

Who told you that?




And 5.0s hardly have any "v8 shake". Sure it's bad enough that it messes up the scale when you're trying to weigh weed but it's nothing compared to the '68 Camaro that I rode in a while back with a 454.

so you put in a rebuilt bottom end with all new rotating parts, rebuilt the trans and the vibration is still there,

did you re-use the throwout bearing for the clutch?

what kind of bellhousing is on there?

is your trans crossmember modified for the 3650 trans? the mounting point is rearward around 2 inches.

what driveshaft? if the driveshaft is too long it could be pushing on the trans, pushing the flywheel and the crank into the bearings.

man when you get a chance take the belt off it >> start it <<< if there is no vib; check the water pump
when the barings go in them they will vibrate >>>>>>> Just a thought.
