You don't think a 12 foot long 10x`10 oak barn beam weighs 300 pounds? It sure does not feel like a hundred pounder .
We got my buddies 2.2 down to the case today . I did a top end on it in 2004. Car runs perfect, but we hear a definite rock knock . #5 seems to have a lot more wobble than the others .Someone rebuilt the whole thing in 87. They used blue rtv to seal the case halves.
We will open it up next weekend
