buy a set of hyd retro lifters and push rods and keep going you will have to do the new chain set and a cam button if you put it in the older block like this.i made up this stuff but you can buy a cam that is better then the older cam tpi and will fit in your block the dog bone could fit in the block with alot of grinding in the block as the water jackets will hit like you said they sell a kit but i never used it as they sell one on E bay looks very 1/2 ass and if you cut to much your block will be junk and you use a roller from a nother GM lifter as the oil band is not right for the older V8 block as the liter bores are taller in the hyd GM roller block the lifter bores are much shorter in the 400 block so you tpi stock lifters will not work
