360-360 crate engine issue

I am starting to get cornfused with my friends 360 that runs like a turd. This is a brand new crate engine, has 125 psi compression in all cylinders, new 6-AL box, tryed 2 new carbs - 750 holley and 650 edelbrock ( brand new), and its a turd, it wont even spin the tires. I have the timing cover off and am going to check cam timing this weekend as well as top dead center. Timing is 12 degrees at idle and 32 at WOT. Any thing that I am forgetting about? It fires right up and idles fine. I assume this thing should throw you back in the seat till you let up.thanks. Don
