You would get piston slap. However, I suspect that the noise you refer to may very well be timing a bit over advanced. I have no experience of the Big Seven engine, but, as a starting point, I would set the static timing at top dead centre and see how you go.
On my RP having set the timing up, I always end up fine tuning it on road test! But then the parameters for sorting the timing out are probably a bit different.
