Default 427 SO block or 428 CJ?

I know some of you guys have road racing experience.

Okay, after my second engine oiling issue, I've got to consider some engine block choices.

A quick history, about two years ago, I lost the rear main bearing, from oil starvation. Re polished the crank, new bearings, new oil pan.

Everything was good, even did a track day last year. I liked it, but was basically going fast on the straights, and crappy on the corners.

I was looking forward to track day this year. Studied the track lines, and planned on working on cornering.

I also arrived with a revised suspension. Wider front tires, and changed rear suspension.

The cornering capability was remarkably better. I spent my time on the track, taking it easy on the straights, and working on trailbraking, track line, and exits.

As I got better, I started braking later and harder, until I spun out. After the spin, I got back to the pits leaking coolant. I found the fan/alt/water-pump belt missing.

Cut apart the filter last night, and can see the tell-tale copper flakes. It looks like another oiling issue.

So the generic 428 block, has oiling issues.
My engine builder, says if I'm going to road race, I need to rethink the engine, and get away from this block.
He has a standard bore 428 CJ block, but maybe I am better off looking for a side-oiler block, because of the better oiling properties.

Can the 428 cj be set up properly, to have adequate oiling, or should I be looking at an aftermarket 427 SO block?
