FST;

Your 347 combo is pretty "healthy" at 450hp, to get another 100 hp out of it, your going to need some serouis stuff, ie.,more cam,more compression, cylinder head work,probably more/better carb,and possibly a stronger bottom end to handle 550 hp........

Getting in the 450 hp range is not that hard to do with the right combo of parts, but as you try to move up the hp scale,you will have to spend a lot of money for small gains, assuming you stay with a carbed motor and no power adders........

I think the easiest,cheapest, and quickest way to go would be to add a super charger, many,many on the market to choose from.....
