help diagnose* this problem

[jonk00000]

my car vibrates horribly on acceleration, deceleration, free rev, clutch in or out, moving or not. its worst around 2k- 2500. i just pulled the tranny because i thought maybe flywheel bolts loosened or pp bolts loosened but they're all fine. motor mounts are fine.

any ideas please help

balance shaft removed

theres almost 20,000k on block and head stage 2 block stage 5 head from slowboy and i rarely get on it. could it be motor problem ??

It could be. Is it missing? Not firing a cylinder?

 

[jonk00000]

nah, car seems to be running perfect. steady idle, vac is good. but as soon as i rev, vibrates

 

[jonk00000]

any way it could be an ignition problem ?

His balance shafts are removed.
A harmonic balancer has nothing to do with engine vibration. It's for crankshaft windup, which won't be felt outside the motor.
Check your driver's side halfshaft bearing carrier bolts on the back of the block.

it vibrates when the car is not moving, clutch in or out.
