Default In laymens terms the difference is

The side oiler oils the rods & mains first then the top of the engine ie valve train.
The regular FE like a 390 or 428 oil the top of the engine first and the rods and mains last and that what has caused many bearing failures at higher RPM.

Also the FE mains are drilled so that once a bearing is installed there can be as much as half the oil hole not matching the hole in the bearing and all FEs should have the oil openings opened up to get full lubricaion to the main bearings.

We're talkin NASCAR motors here, .....not the local stock drag strip machines or street rods.
There are about a kazillion FE motors out there that make great HP and hold up just fine and are not Sideoilers. If you have a legit purpose for a sideoiler...go for it,.... but other than that it's just "pissin rights".
Just my opinon, Old Bill

And most of the FEs around here are strokers anyway. And most of those are SCATs, and that means they ain't Ford no mo'. They're more Chevy than anything else (mine included).

I have a solid cam and a SCAT lower end, along with a rev limiter set at 6400 RPM. I try and shift at just over 6000, as there is no real point in going much over that. But ocassionally I bounce off my rev limiter when I'm not paying careful attention. I have no doubt she would waltz past 7000 if given the chance. FWIW, here are my shift points based on my gear ratios and torque curve.

Look for the cross-bolted mains that a 427 has. Here's a shot:

As Patrick said, look for the cross bolts (bolt heads) there'll be three of them on each side of the block just above the oil pan rail. If the engine's in the car, jack it up and you should be able to see it from underneath. This'll just indicate whether it's a 427 (could be side oiler or top oiler). Heck it could even be an "cross-bolt" aftermarket mod to a 390 or such too.

It will always be a 390 or something worse. It's only a 427 in fairy tales and other people's posts. If it's yours, it'll be cracked truck block.

The original racing snakes came with 427 side oilers and cross-bolted main bearings. Occasionally 428 top oilers were used though it was totally different engine. But as Carroll Shelby once pointed, it was pretty hard to find difference between 425 and 475 bph if you were not a racing driver!

Default common Cobra misconception

Yes, the RACING Cobras may have had side-oilers. But the big block Cobra production cars were split roughly into thirds. The first third had center-oilers, the second third had 428s, and the last third had side-oilers.

The fourth third? I never did get this new math, anyway.
