Re: block question
if your planning on doing 4 bolt mains i wouldn't do it, its a constant fight but i personally have looked at blocks side by side and there is less meat in the block. My local machine shop won't do 4 bolts on a BS block. Another thing to keep in mind is that the cams from a syty or non BS block won't work in a BS block. Also the BS block your stuck with the crappy stock timing covers. But its hard to tell how much weight to put behind the non BS blocks being stronger.
