Thundercat,
Who is building you engine, and what bearing clearances will you be using? Most of the 428 FE's I have seen, have larger clearances, and should get more flow. The size of you AN lines/filter configuration, in conjuction with the standard SPF
oil cooler should be reviewed.
Southern Automotive (they did not build my engine) could be a starting place to see what has worked before, as they have built many engines for Superformance cars, a lot of 428 FEs. Doug Reed is the owner of the dealership in New Orleans, and he also has much experiance with and without coolers on 428's.
For the most point, I agree with what 427 sharpe said above. If you are going to race it, get the cooler hooked up. if not....most likely you will not need it. But
oil wgt., clearances, flow need to be reviewed, and if possible, follow others that have your set up for the way you want to drive.
Sign up for the SCOF board now that you have your car. Lot's of specific SPF stuff there too!
Great Asp
PS congrat's on getting your car!
