8N Industrial Engine

[rbuckel]

Probably been asked a few times already, but why did Ford make the 8N Industrial engine with no sleeves?

rbuckel.......Ford DIDN'T......its been "hot-rodded" and rebuilt with NO sleeves and '40 Merc pistons. More cu-in equals more power. Simple, eh? .......Dell

8n with star after eng number has 040 sleeves.
With diamond after number, it has 080 sleeves.
The star engine can be run with no sleeves and .083 or .100 over pistons. With power dome pistons and a GP cam, it will put out 34-36 HP
@2500 rpm., and 50 hp at 4000 rpm. on 87 octane.
Add a 2bbl carb and a Sherman head,,, who knows?

My dad rebuilt our 8n with NO sleeves and '40 Merc pistons in 1958. It worked great for about a year then lost power and started burning oil again. The mechanics of the day in ower area didn't think the cast used in the block was high enough quality to run a piston in. Was the ford industrial made of better stuff ??

Industrial engines were produced sleeveless with a standard bore,,, the same standard bore a sleeve engine would have with the sleeves installed

BTW they also did not have harden valve seats

We tore on down at a Massy dealer I worked for, and someone had taken the sleeves out and put oversize rings on the stock pistons.(didn t work very long)

The others are confusing a tractor engine with you question,,, I spec the industrial engine was not as acceptable to ware issues as the tractor engine,,, no sleeves and other upgrades to ware parts would have made the industrial engine cheaper to produce....

Whats the serial number stamped on yer block,,, that would answer some questions....

I believe you are correct. I over-hauled and used std rings. For now she is running great and is used every summer to rake hay.

It has an industrial engine plate on top of engine behind head. No S/N what-so-ever on side.
