Geneo4116 Posted January 16, 2014 Report Share Posted January 16, 2014 I know it's a 5.8 so that means a 351 right,but is it a Cleveland or Windsor,or am I just thinking old school,I mean the heads are massive,so maybe it's a big block or is small block and big block over now,in this new world ,WHAT SAY YOU .........

Rattlesnake Posted January 16, 2014 Report Share Posted January 16, 2014 Good question to ask... Classifying either a small-block or a big-block has nothing to do with displacement, but the distance between the middle of each bore. Small blocks therefore are smaller and can generate more heat, which could be a bad thing Large blocks are larger with bigger distances between the bore and therefore could run cooler. More room in a big block to have a longer stroke and bigger bore. Also they are usually heavier. Small blocks are now made of a great mixture of metals and can withstand more heat. The 5.8 engine is a 5808 cc, 354 CID DOHC 4-valve Modular V8. Link to comment Share on other sites More sharing options...
Secondo Posted January 17, 2014 Report Share Posted January 17, 2014 In old-school talk it's a small-block 354 Romeo (named after the Romeo engine plant). Code-named "Trinity." Link to comment Share on other sites More sharing options...
2112 Posted January 17, 2014 Report Share Posted January 17, 2014 Tho I agree it is a small block, it has many of the external dimensions of an old school Big Block. Particularly width. . Link to comment Share on other sites More sharing options...
ChadBuckWeb Posted January 17, 2014 Report Share Posted January 17, 2014 I was under the impression that the Trinity is a big block. I know I've read that somewhere. Link to comment Share on other sites More sharing options...
07SGT2899 Posted January 17, 2014 Report Share Posted January 17, 2014 the terms big block and small block are kind of obsolete now, especially being that ford only produces one type of v8 block/engine currently. the engine is refered to as being in the modular engine family.

Geneo4116 Posted January 17, 2014 Author Report Share Posted January 17, 2014 So what ur telling me I think???? Is that there ain't no big block are small block anymore,it's just called a modular motor, my brother just bought a raptor,with the 6.2 engine,is that a modular engine also?

07SGT2899 Posted January 17, 2014 Report Share Posted January 17, 2014 yes, all ford v8 and v10 engines are of the modular family, all sharing a number of design features google modular ford engines and you will find some good reading on the interchangability of many their parts Link to comment Share on other sites More sharing options...

Yes, Raptor is also modular. When the big blocks disappeared the term small block disappeared. The last big blocks were 460s in trucks through the 90s sometime. I know it was offered in 94 because I considered one in a new truck. Tom Link to comment Share on other sites More sharing options...

yosemiddysam Posted February 4, 2014 Report Share Posted February 4, 2014 Where did Ford squeeze the extra .4 from a 2012 5.4 to a 2013 5.8? Link to comment Share on other sites More sharing options...
JeffJ Posted February 4, 2014 Report Share Posted February 4, 2014 Where did Ford squeeze the extra .4 from a 2012 5.4 to a 2013 5.8? Even though they look pretty identical, there were MANY changes internally to the 2013-14 from the previous 5.4. However, the increase to 5.8 was due to an increased bore and piston size. 3.552 bore with 4.165 stroke for the 5.4 3.68 bore with 4.165 stroke for the 5.8 Link to comment Share on other sites More sharing options...
yosemiddysam Posted February 4, 2014 Report Share Posted February 4, 2014 So in theory......Bore out my engine and I will be the same size lol. Thanks. I would like to try a Compound boost application on mine. Once I hit the lottery that is lmao. Link to comment Share on other sites More sharing options...

When Dodge did this with the 5.7 Hemi to get the 6.1, the general concensus was that if you want to put a BIG blower on it, use the 5.7. I don't know what the folks like Kenne Bell and Whipple are recommending with the 5.4 vs 5.8... Link to comment Share on other sites More sharing options...
JeffJ Posted February 4, 2014 Report Share Posted February 4, 2014 While dimentionally it is the same, there were some internal changes made for the 5.8 to be stronger, at least that's what they say.... Link to comment Share on other sites More sharing options...
440sprint Posted February 6, 2014 Report Share Posted February 6, 2014 Ford uses a spray bore in order to keep the 100 mm bore spacing and avoid a bore sleeve. 5.0 Magazine on the Trinity engine: Ford's approach, first used in the 2011 GT500 block, differs in that it is a post-casting, dry application of molten iron, resulting in a thin, durable, lightweight, oil-holding metal lattice joined to the aluminum bore's surface. The process is called Plasma Transfer Wire Arc, and was developed jointly by Ford and Flame-Spray Industries in Long Island, New York. Besides the GT500 blocks, it's used in gas turbines and Caterpillar remanufacturers its diesel cylinders with it, so it's tough stuff. Ford says the iron liners removed from the 2011 GT500 block weighed 7 or 8.5 pounds (depending on who you ask), and the PTWA coating is only 150 microns (0.006-inch) thick, so little weight is replaced.

Was the un-sleeved bore increased or was the displacement reduced when the 5.8L was sleeved? Was the reason for the sleeving mentioned? Was the stock block used?
