Only thing that could be questioned, IMHO, is the "high volume"
oil pump.
More distributor gear/cam gear problems caused by those than anything else.
Unless the engine is being built with "racing" bearing clearances, (wider than for street) I would suggest that the a std
oil pump would be just fine, and reduce the strain on the distributor drive gear.
My own 408 stroker is very similar spec to yours, std
oil pump works just fine, in fact I suspect the pressure relief valve on it is open most of the time, suggesting more than adequate volume being produced.
Would be interested in other opinions on this.
