Canton Oil System diagram
Here's my oil system setup.... all Canton parts, 2 oil filters, a oil thermostat to control flow through the oil cooler, check valve and the accusump.

Cooling fans control & fuel pump safty switch
Cooling fans... ah, the hot south... I ended up with the two traditional pusher fans and then added a large pull fan behind the radiator. You notice in my electrical diagram, I have a switch on the dash that will be "ON" as the normal setting, but the ground will be conntected to a sending unit that monitors the water temp. When the temp reaches 200 degs or higher, the sending unit switch will engage and cause the fans to get grounded, therefore, turn on. You'll note in the picture a second sensor in the package. This is a safty shut-off switch for the electric fuel pump incase of an accident. The way it works is if the eng stops, and no oil pressure, the sender switch is opened and the power is killed to the pump. At eng startup, with no oil presure, the sender passed power from the starter to power the pump.... so, while starting, power from starter to pump, you make oil presure, which in turn closed the sender switch to power the pump from the normal "on" power vs the starter.
Dart 427W link and writeup
I just found this site that might be useful to someone considering a DART block
Here's a highlighted paragraph:
The Dart block replicates the original Ford 351W in terms of basic design and layout, but with several enhancements. Cylinder walls and decks are beefier, allowing much more custom machining latitude. The block also features priority main oiling system. The block material itself is much more rigid (high nickel alloy content iron block) and much more suited to high performance and/or racing applications. The main caps are machined billet steel, anchored with four bolts each (with splayed outboard center caps). The block also requires the use of a crankshaft that features Cleveland-sized (2.749”) main journals for added robustness. In short, Dart re-engineered the 351W block to meet today’s performance requirements. Basically, the Dart block makes the original Ford W block look like the skinny kid on the beach. Dart’s block is a brute, which basically blends the best from both the Windsor and Cleveland designs, along with Dart’s own performance enhancements.
