One time long ago i built a 428 Cobra Jet engine. I went to Ford and asked them for a 428 CJ Flywheel. The parts guy gave me a 429 flywheel by mistake. I went back to the shop and installed it. Bolted up just fine. Got the whole project done and started it up. Vibrated pretty bad. I thought it was the flywheel. I asked the parts guy to ck the number. He apologized and said he gave me a 429 flywheel. Long story short, i put the correct 428 flywheel in....smooth as butter. Point is, i know what a flywheel vibration feels like.
Here are my questions:
[Conditions:
Im using the Whitbread 30 lb. Flywheel with the Clutchmasters FX-250. And the BS is deleted. To the Alh pump, Brm pulley version. Not the geared delete. I just completely rebuilt the motor from the crank up. New rings, bearings, light diamond hone, rebuilt head, only 200 miles on the rebuild at this time.
I have a vibration. Its not terrible, but its there. All the way through the rpm range]
Is the vibration from the BS delete?
I checked the rods. None are bent. Injector balance is 25% or less of the allowable deviation from 0.
Or is the 30 pound flywheel/clutch assembly out of balance?
Crank pulley bad?
Engine not broken in yet?
Anyone with the BS delete (non geared) without the 5sp?
What do you guys think?
