OK Guys,
Seems that I have bad luck, and will need some advise.
Got a lot of work done to my car recently. Everything is pretty much over.
I have to say I am pretty much disappointed / like I am sentenced.
The engine vibrates on the whole rpm range.
Lightly down low. If above 4000 rpm it is very noticeable.
I chased the front pulleys, change WP, WP pulley, serpentine and changed the tensioner, also realigned the all set perfectly.
That's not it.
You can feel the vibration mainly in the shifter handle. Clutch depressed or clutch in. In gear driving or idling. The vibration is present. Gets worse with engine speed.
I made a test on a cold engine when I chased front pulleys related vibration, and before I reassemble everything --> and it seems they was no vibration at cold? I went up to 4500 - 5000 rpm.
This is my engine BluePrint Engines 383 CI Stroker Crate Engine | Small Block GM Style |
I have a T56 LS1trans. This trans is perfect, it was on my previous engine, no change.
I installed this clutch and flywheel from Mc Leod:
MCL-75225 SUPER STREET PRO CLUTCH
MCL-460360 FLY WHEEL
MCL-560222 COUNTER WEIGHT KIT
Also got a 400 cid vibration damper from BPE, comes with counterweight.
Chevy Small Block Harmonic Balancer - Externally Balanced – BluePrint Engines
This is the install of the flywheel and counterweight in position C:
Everything bolted to torque specs, right Loctite thread locker used, etc, etc.
I will write to Mc Leod and BPE to get their advise.
I think I am fed up and worried to the point I may bring the assembled engine with clutch on to a local engine race shop that they would trace and correct things and test it.
Any support appreciated.
Marc
