converting 2 bolt to 4 bolt

[markss28]

I have a 2 bolt in my car right now and I have all the parts to build a new 383 stroker with crank , rods, pistons and all. All I need is a 4 bolt but they seem to be very hard to find or a bit pricey. I have seen on line a few engines converted to a 4 bolt and was wondering if that was a good option.

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