Engine Vibration at Idle 1989 Camaro 305 TPI
Hello
I have a vibration problem after engine rebuilding at idle and up to about 1200U/min.
I only reused the crankshaft (grind to 0,01 under) and the connecting rods. All other moving parts are new.
The following has been checked.:
-Torque converter
-Ignition system (timing, misfire, ...)
-running without belt
The old pistons were 15g heavier than the new ones. Can this lead to my problems ?
Thanks

Yes you need to have the rotating assembly re balanced.15 grams difference is a lot
