Hawkrod,the point I was making was that D3TE and D4TE blocks were cast with thicker cylinder walls for heavy duty truck use and if there was minimal core shift which Ford could determine thru inspection then the block could be machined to 4.13 bore.I find it hard to believe that Ford would recore later block molds to cast up some blocks simply for service use. There is plenty of evidence to suggest that Ford cast some blocks with thicker cylinder walls and would inspect some for use in applications they were not originally designed for.Case in point would be the very large experimental483 cubic inch motors Ford built to put in a Starliner and take to Bonneville in the early 60's.Those engines were built around a 406 block that was inspected and found would accept a .100 over bore to 427 size.This predated 427 production by at least 2 years.Industrial engines are another good example there is absolutely no rhyme or reason to what Ford was doing there,bottom line is they used what they had available and would work. |
