Thanks guys, once again, I´m using the 1956 chevy engine with original pulley and harmonic balancer on my 1952 chevy truck. I repositioned the radiator to the front to have the right clearance. I was thinking that I had the natural installation for the engine(of course in other truck), but there is something I´m missing? On my first truck I had the same situation and never suffered whit it.
I want to read all your ideas.
