There was a great discussion on the 2F vs Chevy motors in FJ60's recently. I have purchased a nice FJ60 with a bad motor so I am in the midst of the decision on staying stock or going V8. I was leaning stock until I learned the weight of the rig is much heavier than by FJ40! What I am seeking in this post is not advice on which way to go, but for education of the types of Chevy V8's. I have heard small block chevy, TBI, Vortex, and perhaps other terms applied. Could someone review this or point me to a basic website? The last Chevy V8 I had was in 1956 in a 34 ford truck; it was a 265 bored out to 283. A lot has happened since then that I have not followed.
