Block Strength
I may be missing the point but sonic tests on blocks I have used showed the "thinest" area between the cylinders - the sides. The front/back of the cylinder (facing the intake or exhaust manifolds where much of the rod pressure is) had plenty of meat.
I am currently running a 4.1x4.0 on a siamese resto block and had seriously considered going to bigger on the bore ... there was plenty of meat on the block but not enough cash in the piston budget.
And yes ... I know resto blocks are not supposed to be siamese ... I know of one other one so there are at least two. I don't have a picture looking inside at the water jackets but here is the block ...
