Engine Value?

[Dimis]

Well here's a question with many answers...

If it were me buying then I'd approach it with "my" value system, that I accept may not be the norm or even the popular consensus.

But for the sake of the argument here goes:

If in an ERA as per your post, I'd be inclined to pay the same as a 428 or stroked (390) 445. ie: I wouldn't be influenced by it being a "real" side oiler. I'd put other parameters ahead, like build quality, general condition and even colour.

If it were a "real" CSX (as in 3000series), then sure I'd pay more for the privilege of a real 427 side oiler over a 428.
However at the same time if it were in a kirkham I wouldn't. Id prefer to chase a car with a new aftermarket Aluminium block. And it be more desirable to me if it were stroked. I'd be inclined personally to overlook a kirkham with a real 427 sideoiler or other cast iron block in favour of the aforementioned.

If spf or ffr or other I'd be inclined to hold off for a stroked sbf, than purchase one with a side oiler. It's not to say I don't appreciate those who build cars with side oilers in them, it's just that I wouldn't spend the extra coin on that bragging right myself.

Cheers
