RE: 390 v 427 side oiler info |

There are quite a few 427 blocks out there. There are the true side-oilers, which are expensive due to the long drilled passages, with side drilled taps into bearings; there are the hi po side oilers with the fully communicated crank, that acts as yet another oil gallery; there are marine 427 blocks many of which (not all) are cast as side oilers but not fully machined, so they are the "center oiler" or "top oiler" version; then there's the bastard two-bolt hydraulic cammed 427 built in small quantity for the 1968 Cougar GTE, only 358 of which were built with this detuned 390-HP version of the 427.
Now I always thought the history books said the 406 testing program was what caused Ford (according to engineer Scussel) to build a 4-bolt (cross bolted) 406 and then 427. I have heard there are a few cross bolted 390's, but these must have been built from the 427 castings or something, on a custom race-only basis by Ford or Holman Moody.
the guys are right, there's nothing you can do to a normal 390 to make it a side oiler, due to the fact that it wasn't cast as a side oiler with the appropriate bulge in the driver side of the block. Of course, there are kits to do this, for a price, but they rely on external plumbing, etc.
Ford once said, and Shelby seemed to agree, that a side-oiler in anything other than a full race machine is a waste of good machinery. For those guys, "full race" means endurance racing like Daytona, Sebring, LeMans, and NASCAR.
