But what are you going to use it on? That's the real question. But I will say go with the one that's most complete and known to be good, as your "first rodeo."
No clue what it's going into. Stock parts in bottom end minus the cam it came with. Came with the 350 heads but may put vortecs with the steam holes in it. Then sell? Buy something to put it in then sell? I have no clue. This is just so I can learn a bit.
