Not that tight??????
I am a fairly hefty lad, and using a 2 & 1/2 foot breaking bar I nearly popped my shoulder out trying to get the main caps undone...the big ends were fecking tight as well!!
You must be getting weak 1 to 8 are 53 lbs ft. 9 and 10 68 lbs ft and side bolts 33 lbs ft. 68 lbs ft max is hardly tight. Wait til you do a Cummins diesels head bolts at 600 lbs ft. You hold the bar at the end not a quarter way down it.
