Hi guys! I am looking at buying an 90 302 Black Thunder with twin 454 mags and hoping that you could tell be anything about them such as speeds with stock power and how they handle and common problems. I am far from a newbie to boating and older boats and have just finished my second transom replacement earlier this winter so I already know how to look for rot in general but wouldn’t mind info on any specific to the 320 BT.
