a few years ago someone tested the metallurgy of an early block vs a late model and I believe they put the nickel content myth to rest. the forged piston were until mid 92, after that they ran hypereutectic. if its a stock shortbock that's never been apart you can tell without tearing into it by the oil pan color. the forged piston engines had a grey pan that matched the paint on the block. the hypereutectic engines had black oil pans.rmyauck wrote:Hot Rod magazine said years ago that the 87-93 302 block used in Mustangs & Lincoln's had a better alloy (maybe more Ni etc.) for more strength and they used forged pistons till 92, with the 93 's getting Hypereutectic pistons. I do believe one of the aftermarket block maker makes an LS engine with Cleveland 2.75 mains also!
ok. for Windsor class (8.2 and 9.5) and Cleveland/modified they are 4.38 bore centers.In-Tech wrote:Considering I know very little about Ford Blocks as well, maybe one of the Ford guys here could post the v-8 block sizes, like Bore, Deck Height, maybe Main Bore. That would sure be helpful.
All modifieds, 351M/400, had 460 bell-housing bolt patterns and were the same deck dimension = 10.292" / 10.302"cab0154 wrote:ok. for Windsor class (8.2 and 9.5) and Cleveland/modified they are 4.38 bore centers.In-Tech wrote:Considering I know very little about Ford Blocks as well, maybe one of the Ford guys here could post the v-8 block sizes, like Bore, Deck Height, maybe Main Bore.

for windsors: the 8.2 uses a 2.25" main, the 351w uses a 3"
8.2 deck: the 221 was 3.500x2.87, (the smogger 255 of the late 70s was 3.68x3.00), the 260 was 3.800x2.87, the 289 was 4.00x2.87 and the 302 was 4.0x3.0. up until about 64 during the 289s they were 5 bolt bellhousing blocks. then they started making the 289s and all the 302s were 6 bolt bellhousings.
9.48/9.5 deck 351w was 4.00x3.50.
the Cleveland was 4.00x3.50 also, with a 9.2 deck and 2.75" mains. the modifieds were kind of a hodgepodge which used 3" mains. the 351m I think was a 9.2 deck also, the 400m was a tall deck 351m, I think 10 or 10.2 deck height.
What year were the 1999 & 2000 Explorers with the 5.8 liter engine manufactured ...?Joe-71 wrote: I am surprised no one actually mentioned that all the SBF Windsor style engines have inline valves, and thermostat housing in intake manifold, whereas the Cleveland engines have canted valves, thermostat in block, and dry intake manifold with the exception of the Boss 302, which has a thermostat in the intake manifold and water passages for that manifold. The 5.8W was produced up until 1995 in Broncos, vans, trucks, and 5.0 to 2001. Joe-71
Except for those weird blocks that had both the big 429/460 bell housing AND the 6 bolt standard small block pattern. I've never seen one of those in person but I wonder what they were built to serve?Walter R.

A Chevy V8 has plenty of weird unexplained changes too. For instance; the dip stick changes from the left side to the right side in about 1981, why?nickpohlaandp wrote:So many variations with deck heights, bellhousing patterns, different blocks... makes my head hurt. There's no doubt that you can make good power with a Ford based mill, but I expect that the seemingly endless variations even within the same engine family are why so many people choose to build Chevy vs. Ford. There's more parts interchangeability and it's cheaper.
Change in dipstick location isn't nearly as critical as the potential for one small block head fitting another. Of course you could make this mistake by trying to put some quality aftermarket heads on a 305 Chevy, but with Ford it seems you might be ok with the heads but later find out you're screwed on the bellhouding pattern.
