Anyone have this problem with a TBI swap? It only happens when under high power for 30 minutes or more- i.e. highway driving with 42's and a 7000 lb pig Engine temp is normal, the tranny gets a little warm as I would expect. Stock puter, mild cam. It's been this way ever since the swap, starting with 37's, 38.5's then 42's. Stock manifolds, if that makes a difference. Ideas? Thoughts?
