340 Engine Shake

that sucks , seems it happens often these days , just hope my 340 don't suffer the same fate once i get it in the car , only has dyno pulls and break in so far , but with all the QUALITY parts on the market today who knows ?
You got no miles on the engine , who covers the cost of a rebuild ?

Yea, I dont know. This is on me as I put it together. I should've just left well enough alone. Lol. I put the 4 speed in and thought I would upgrade the heads and cam. Oh well.

It's just disappointing, that I have had this thing since 2013, rebuilt from the ground up and still haven't been able to drive it for more than a summer due to one issue or another. *Sigh*

I'm getting pushed to put a roller in it and be done with it. I'm gonna get it trailered home and start tearing the motor out soon.
