might think about cast alum instead of chrome plated steel. i don't know if i have ever seen a 250 chrome oil pan. a lot of the import stuff is pretty cheap made and won't look good for long. that's a good idea about chroming your orig parts you would prob have good luck with that. the cheap stuff starts rustin' out pretty quick. alum valve cover, timing cover and lifter gallery covers may tarnish a little, but will still look presentable for years to come. more ridgid for a better seal to if you get a goos one. hr
