427 NASCAR engine cannot be identified by "looking" at the outside. The difference is "internal". Beefier components, crank, rods, etc. Even there you would have to KNOW what your looking at to determine a NASCAR rod from a standard 427 connecting rod, etc.

And whats up with the Side Oiler vs Center Oiler thing anyway? Like YOU could tell which was which? I bet you would be hard pressed to find ONE person at a "car show" that could tell the difference between the two motors by simply "looking" under the hood!

So whats the big deal here? Bragging rights (and yeah, that has some value, no doubt about it). MORE bragging rights with a NASCAR 427 than a standard 427 SO and less bragging rights with a 427 C.O.

The S.O. engine was preferred because of the superior oiling system delivery to the BOTTOM of the engine first and the camshaft and upper area next. The C.O. delivered to the upper area first and the crank next. Real world, some street and track driving advantage? Virtually zero, in MY opinion. ALL can be built to the same horse power.

IF your going to run the engine at 7000 rpm for HOURS for ONE race, you might want the NASCAR or at least the S.O. IF you still want "bragging rights" and want to save BIG bucks, go with the C.O. and TELL people it's a S.O. (not one in a 100 could tell the difference).

What the hell, now that we know your a LIAR, tell 'em it's a NASCAR 427, there is no way they could say your wrong without tearing the motor down!

When I hear a guy saying HIS 427 is a NASCAR motor my first thought is:
'OK, somebody took this guy to the cleaners, slim chance thats what he really has'. But I will smile and say, "Cool".
