From my research, the ribbed block means that there is no way this block was ever used in an OEM 427 side-oiler installation. From what I read, the last OEM 427 side-oiler blocks were cast in 1964 (without ribs), and were installed in 1967 model year cars; while the ribbed FE service blocks did not come out until the early 70's...

Now, even with the service block, this engine might still be machined and built to a cross bolted main configuration (I've read that some service blocks did have the provisions for the cross bolts), but this engine block never lived in an original 1960's 427 equipped vehicle. No way.

I know all this because I talked to the seller of this engine on the phone many months ago, and then did some homework

This ad (or other ads for the same engine) have been up in the Arizona Craigslist for several months. The seller wants to sell it as-is, for big cash, without putting it on a run stand so the buyer can hear it run. The seller was also suspiciously not forthcoming about why the engine was removed from the car after only 1000 miles...

It's a mystery-motor, that he's asking pro engine builder money for....

The only way you would know if this engine was any good would be to manually compression test it (cranking it by hand), and then remove all the bearing caps and plasti-gage all the bearings for tolerance, then spin the oil pump with a powerful drill to make sure it makes oil pressure, and then pray that you don't have a spun cam bearing, cracked water jacket, or collapsed lifter inside there.

(or, you could ask the seller if he would be willing to let you install it in a car before you paid him for it, but that proposal didn't work when I tried it , haha)

I suggested to the guy he should probably put it on a run stand if he expects to sell it for that kind of cash, but it seems my advice was not heeded...
