Difference Between Fox Block and SN95 Block?

[onefstsnake]

I picked up a motor from a buddy of mine, but its a 94/95 Shortblock w/E7 heads.

Anything different about the SN95 blocks?

Also whats the best way to clean it without having to pay someone? lol

 

[jrichker]

The blocks are the same as the eariler 5.0's. The one thing different was that some of the 87-91(?) engines had forged pistons.

87-91 had forged pistons. Mid year 92-95 hyperutectic.

ahh, the imfamous porno block.

 

[onefstsnake]

Well the entire rotating assembly is going in the trash unless anyone wants it.

Im going 331. Just wanted to know if there was anything different in the block it self.

I just bought the complete engine cuz it was cheap $300 for a 30K mile engine.

cylinder walls still have a nice crosshatch and everything.

So are you saying my 93 has those ****ty ass pistons? peace

Yep.

The old generality was that forged-piston engines had grey oil pans and hypereutectic-piston blocks had black oil pans.

Well that just motivated me into getting the 408 rolling even faster! peace

Interesting. Never heard that one before. My 93 has a gray oil pan.

Yep, Agreed! My 92 was built 8 Months into the 92 Build Year and its Grey!

 

[Kumm3]

so if i paint my oil pan grey, my pistons become forged?

Nope, if you scrape the black paint off your oil pan (revealing the OEM grey that should have come on an '89 motor), you're set.

Only 93 had them. 87-92 had the TRW forged.

um, i dunno where my stock motor even is at this point........

boat anchor maybe? (where it should be)

Correct!

There is still some debate about this. I've heard of quite a few people with 92s built late in the model year with hyper pistons, thats why I said mid year 92.

 

[HISSIN50]

I've come to accept the same thing as Pacecar states. In any event, it's the safe statement to make (erroring on the side of caution with regard to thinking one has forged slugs and ends up not having them).

Car makers generally dont have things together enough to precisely run-out of a product right at the model year change, ergo mid-year changes.

 

[v8only]

agreed, and they're certainly not going to throw the leftovers away, or create a whole new batch of the old just for another 2 months of the run.

 

[Shakerhood]

If there are any in 92s I would say it came at the extreme end of the production run before ramping up for 93s as 92 was the least produced GT of the 87-93 cars, I would tend to think they had extra Parts moreso than running out of stuff early.

OT .....


Anyone know about the Explorer/Mountaineer, F-150, and other car engine's? I have a '97 Mountaineer in the garage that I'm pretty sure has hyperuetetic's. I also have an early to mid '90's F-150 out there. It has a gray oil pan (but different than our pans, of course). What would the F-150 engine have in it?
