Dom, i used to run the 15/50 Dominator by Amsoil in my small block. Holds viscosity very well. Expensive, but a great product. I will be using the Dominator 20/50 next yr. Thats what Amsoil suggested for my street/strip deal.
No 20w50 ever for me but will check it out further when time permits......
