I just rebuilt my engine... (shortblock done by local shop) its now a 335 stroker... My question is, how much engine vibration is normal? heads are WP SR Torquers, Cam is Comp Cam 262, Stock Qjet... I still don't have it tuned that well but it runs... Timing is still off I'm sure... But it seems to vibrate quite a bit... It is kinda cool to a point but its almost alarming... feels like I'm in a nascar or something... I know my timing mark is off on the damper, so it might have other issues as well... I might just try changing it and see if there is any difference...

 

Vibrating or running rough/choppy?

You should get a new dampner....it is most likely your problem especially if it's already slipping off the timing marks.

 

I didn't see in the post if it was an automatic or a stick shift ??

what caused you to rebuild the motor ?

I had a similar problem with my car when the FOOL who owned it before me decided to drive it a about 80 with no oil, you guessed it, BOOM, two rods said BYE<BYE. at the same time it tore the torque converter up when the motor went from 3000 to 0 rpm in about 1 sec.

just food for thought !!

 

The engine was running fine... It had about 150k on it... Just wanted more power... It is an auto... has a new PI Vigilante converter...
