Default off set ground crank???

I have a early steel crank for a 440. Which is pretty bad shape, been setting around for 10 years or so. So how far can you turn these things and be safe on the street? How about odd bearing sizes like .040 over? I have heard of offset grinding the rod throw to gain 1/8 inch or so (.125) and using cheby 454 bearings if true should be a 460cid engine with a .030 overbore if my math is correct. would this gain make a diff? I would want to put alot of money in a engine so it would fail prematuturly? If any one has done or know some one who has done this please some feed back please?????

Well, offset grounding is done by welding the crank. Adding material to reshape. Is another 20 cubes in stroke worth it?
.040 oversized bearings? I never seen them that large.

The offset grinding to BB chev journal size (2.2") is a popular stroker setup using aftermarket rods. Termed 470 CID, it is a good way to save a damaged crank if not too severely damaged.

I have an offset ground 360 crank that is .040" under. This is fairly common practice especially in the GM camp.
