225 running a bit warm!!!

I saw the pic of your car with no shroud and thought about it. It could help at slower speeds for sure, and wouldn't hurt at higher speed. By the way, what is the condition of the anti-freeze? Is it still clean? If it is dirty already you could try a backflush of the block. Also, if there is too much anti-freeze and not enough water it could get hot, as anti-freeze alone or in too high a concentration transfers heat poorly.
