1998 Vortec 355 parts build Questions

First off this is for a small 18ft boat, I didn't build the motor and there is no warranty. This should be about a 320 hp max rpm 4800 engine

I need to fix #1 spun rod bearing that happened shortly after startup . I believe about an hour of time on the motor on the Water. I would assume the rod and crank Journal are bad. The Crank rod Journal is at .20 already So

Should I buy a new Scat STD Crank for 189.00.
Eagle brand is 20 dollars cheaper but heard scat was better

or

Use a good STD 305 crankshaft I have sitting here and have it checked and Polished and balanced for the 350 pistons for 225.00

I was going to purchase Clevite p series mains and rods for this application.
