   Jim Butler Pontiac has stroker kits to take a 350 pontiac block out to 383 / 407/ or 413 cubic inches. The extra cubes will come from the stroker crank and a slight overbore of the cylinders. Pontiac engines and olds engines are completely differant. Oldsmobile 350's (most '68 to '72 blocks ) can be bored up to 373 ci (stock stroke crank), but you'd want to have the block sonic checked first.
