I am unaware of a ring set for the 4.460" bore....4.440" and 4.470" are the ones I know of.

A "frozen" crankshaft probably means that he had it cryogenically treated.

A 4.47" bore passenger car block with a half-fill of the water jacket ought to hold 750 hp no problem in most cases. Were the block unfilled, I'd like to see a sonic check sheet but even so 4.47" is not out of the question....although it can make most people uncomfortable.

p.s. The ad also says, "1970 truck block with high nodular content." The 385 Series did not come in trucks in 1970, FE Series engines did. And the "high nodular" part, well, I am unaware of any passenger car blocks that were cast with any different material than any other OEM passenger car block. The lifter valley does look to be that of a D0VE-A cylinder block or 1971 D1VE block, and not a D9TE, or 1972 & up D1VE, or C8VE, or C9VE, etc.

my dove-a block is 4.440 unfilled,no problems..........yet.lol

Yep I ran mine for 8 years, many passes!

A standard bore Chevrolet 502 is 4.466" so, maybe they got confused during translation for the add.

Block material being different is an outright lie though.

hey everyone,new to this specific forum came over from 460ford.com


in regards of this engine,i've spoken to the owner of this engine. stated as shown,half filled to the wp holes,has a main gurdle on the bottom end,just freshened from the machine shop custom diamond pistons.

im interested in this engine,but the thing that has me is the 4.460 bore,i'e asked him and he never did get it sonic checked and previous ran this block with 4.460 bore pistons before for est 200 passes.

the block is a d1ve-6015

what is everyones thoughts on the 4.460 bore without sonic checking? what kind of risk is posed from it? looking to put it in a mud truck 4500 lbs and spin it to 7000 rpm.

would like to hear everyones responses before making a decision, thanks

Nobody here can truthfully answer the question as to what kind of risk it is.
I can say that I have run a 4.470" bore block, (more than one actually), with a "half fill" to over 800 horsepower without any incident. However, those blocks were sonic checked before filling to be sure they were thick enough.
