318 best lifting points?

5/16 carb studs have a breaking strength of 3900 lbs and that is grade 2. They have a working load of 270 lbs (X4 on a motor plate) so you are good.
"...3/4 6061 AL plate using a 5/16-18 grade 8 bolt threaded 5/8" into plate had a pull out force ~15000lbs..." Pull Out Force Calculation in Aluminum - Metal and Metallurgy engineering - Eng-Tips
So why are there so many carb stud stripped intakes? :wtf:
