are they as good as they say
I have one i built late last year. From an 82 F100 ambulance. It works the same as any other block. Although, this is the only motor i have ever had oilpressure problems with, but i think is the pump??.(still cant blow it up. lol)pinkbits said:are they as good as they say
Better cooling.........? The bores are actually heaps thicker. As a result of this the outer surfaces of the block had to be moved out otherwise there wouldn't have been much of a coolant passage around the bores. This gives the "pillow" effect that most people believe is for extra cooling. It probably helps in the cooling process as well, but this is only a secondary benefit. The people who usually make "a fuss" about them are engine machiners/builders, as they have had first hand with the limits of the bores on "normal" clevos and "pillow blocks". I would call them experts who know better. (They can probably spell too). The blocks were fitted randomly from 1980 onwards (i've seen one in a falcon ute - factory).ch7472 said:I dont no what all the fuss is about. Something about better cooling? I have worked on all sorts of Fords over the years and have never noticed anything better with one or the other. But I am shore all the other experts will no better.
Yep, "D" block split a bore at 30Racer said:Has anyone ever seen a broken standard 30 over 2 bolt block?
D block yep, ive seen one too, but not a sq block, they are a better quality cating than a D block.RPO-083 said:Yep, "D" block split a bore at 30

OK I 'll be the mug but I am sure there are others who don't know either.4Vman said:D block yep, ive seen one too, but not a sq block, they are a better quality cating than a D block.
A "D" block is an early US casting that was fitted to late XW, XY and early XA cleveland powered Fords (mainly GT's).shaynet said:OK I 'll be the mug but I am sure there are others who don't know either.
What is the difference between a D block and Square block?
I have a Pillow Type Block and it isn't any thicker than any other Aussie Clevo block(black block).pinkbits said:are they as good as they say
Ok, so lets have a little bit of a history lesson about Clevo blocks.4Vman said:A "D" block is an early US casting that was fitted to late XW, XY and early XA cleveland powered Fords (mainly GT's).
It is identified by the casting code D0AE and a "D" shaped hump on the passenger-side top of the timing chain housing.
A "Square block" is the later US and aussie casting identified by the casting code D2AE-CA with a little "square" in the place where the "D" shaped hump is on the block.
XC was the last of the blue block small hole blocks, its a minor change in machining. Id say the XD "chaser" had a change over motor fitted and it was an earlier block used. Allot of American blocks were imported during the 80's and 90's which are identical to ours but dont have engine numbers stamped on them, they were used by engine reco places to provide a change over service.shaynet said:Ok, so lets have a little bit of a history lesson about Clevo blocks.
I have had a look at both my XD ESP & XD Chaser blocks (both 351) and they are both square blocks. Both cars were built 12/81. Presumably both black blocks.
However, the ESP has a large dizzy drive shaft hole in the block but the Chaser has a small hole. Can you shed any light on this? Of course, it cannot be guaranteed they are both original blocks, even though body and engine numbers match
Hang on a minute. Dont the later model bocks have the small drive and the older have the large?4Vman said:XC was the last of the blue block small hole blocks, its a minor change in machining.

Yes you're right, sorry i got them around the wrong way! :hy:grey_esp said:Hang on a minute. Dont the later model bocks have the small drive and the older have the large?
Which means that the ESP has an earlier block. Or the dizzy shaft hole has been drilled out?4Vman said:Yes you're right, sorry i got them around the wrong way! :hy:
