So when I was putting together my short block I was double checking the clearances and thought the center mains were a bit tight. .013 the front and rear measured .015.
I brought this to the attention of my machinist he asked if I had the heads bolted on when I checked it he did the line hone with the heads torqued on.
I just got my heads and plan tho use RJC gaskets to install should I bolt the heads on and double check if I had a set of used gaskets I would use them for this procedure.
Would hate to get the heads bolted on with the the sealant and crush these gaskets and have to get a new set.
Is there that much flex in these block that it would appear this tight without the heads?
-
that is toward the high end of factory specs....I normally set them at 0.0015" and don't want more unless I am planning on turning more than 6000 rpm
-
ahh yes a decimal point off by me .0013 and .0015.......
Should I be overly concerned about the centre mains being tighter without the heads on?
-
I would not
factory low end of the specs is 0.0003"....
