Radiator help......

I drove my 500 Stroker for a season running real warm. Checked into everthing but T-stat. Well wouldn't you know the t-stat wasn't opening fully.

I pulled the stat and boiled it on the stove and confirmed its' a 160 stat that opens at 170-175. ran it for a day with no stat, but a buddy who I trust is going to load a disk in there to slow the churn but nothing mechanical to slow things down too much.
