Let’s say we are at the sb and we shove a 40k stack to the bb that covers us.
We know that he is going to fold 70% and that if we called we have 35% equity
Is this information enough to calculate if this is profitable or not? And if yes how!?

Hi, w4terman!
It's not. It depends on how many Big blinds that 40k stack is : )
If it's 100bb it's one number, if it's 10bb effective, than it's a completely different result 
(Lol, managed to squeeze in 234 errors in my first two edits.)
ES_shove = ES_BB_calls*probability_BB_calls + ES_BB_folds*probability_BB_folds.
ES_BB_calls = pot_size_bb_calls*equity_bb_calls = (1sb + 1bb + 2*effective_stack)*equity_bb_calls
ES_BB_folds = pot_size_bb_folds = (1sb + 1bb + 1*effective_stack)
ES_fold = effective_stack
You take it from here. ES_* stands for "Expected Stack in case *".
Oke, so if effective stack size is 13bb, we push-he calls us 70%(I put power call-22+, A2s+, K2s+, Q2s+, J2s+, T2s+, 94s+, 84s+, 74s+, 64s+, 53s+, A2o+, K2o+, Q2o+, J4o+, T6o+, 97o+, 86o+, 76o-which is 70.14%), our hand is 53o that has 34.12% equity vs this range and this way-it's minus ev. It's gonna be a losing play in the long run by a lil over than 3bb on average. If he calls that loose with that exact range, we need to be pushing about 41% of hands which includes these ones-22+,A2+,K2s+,K4o+,Q5s+,Q8o+,J8s+,J9o+,T9s in order to show profit. I used ICMizer and pokerstrategy equilab.
