Loosing 100 ft lbs in that short of a time and you should be able to see the problem somewhere. You will have to pull ALL the rods and mains to be sure. If the cam spun freely when you put it in, it's not likely the problem. How do the cyl walls look from the bottom? Did you check the rotational torque of the short block when you put it together last? Should have been in the neighborhood of 25 ft lbs. How was the oil pressure? Stay positive. You will find it - hopefully without too much damage. At least you didn't have to deal with taking it in and out of the car again.



I had to go with 4.080 rings on a 4.076 bore so they
were tighter than normal and it ended up at 32# rotational
which is a bit high but I knew where that came from...
the cam spun freely when I installed it... I didnt
look at the bottom of the bores... by then I was done...
this isnt the first engine for me but this one sure
is giving me sh!t... I ran all sorts of scenarios
through my head this evening but I quit guessing...
I'll find out Friday when I get it home and on the stand
I was so pissed at that point I just quit... nothing
else could be done there on the dyno... why pay for
more time..... granted I didnt pull all the caps
but I doubt its a rod... I could slide them easy
on the journals.... but hell maybe I dont know sh!t
now... of over about 150 engines I've built, this one
is killing me..... and its my own... thank goodness
its not some one elses
