Found this add. Not looking to buy just curious. Did these blocks offer 428 cores? I have wondered about the cores in an engine I had. In 100 deg weather, loaded trailer my 69 .060 over 390 never had overheating issues. http://austin.craigslist.org/pts/4504509427.html

Not a 428. Needs a "X", "A" or a "C" on the back of the block. And not all 428's came with extra webbing. ;D

I have always been under the impression that the only true test for a 428 block was the drill bit test, because I thought Ford used different rear bulkhead mold patterns on all sorts of blocks over the years of production. But I am no expert on all the changes (and there are many) that Ford made over the years. One thing is for sure, the drill bit test is a quick judgment as to whether or not it will handle the bore size of a 428 instead of wondering if it just a severely overbored 360/390.

Good post on link Wes. That was the first thing I noticed was this block has the same makeup as my 70 390 I have now. The only blocks I have had that did have 428 cores and webbing were D3 and D4 castings. Guy in add may have straight cores cut to max.

Yep and most likely the block is done , i have 2 428 cj blocks , both have C7ME A and the c on the back , and 428 in the water jackets .. Bud
