Will it have the same stregth as a 4 bolt or just a bit stronger then a 2 bolt?

2 bolt blocks are stronger. They just have less clamping force on the crank.
I say "F" the four bolt blocks. Buy a set of splayed main caps and have your machine shop drill and tap your block for them. I did that to several Pontiac motors and they all ran great.
