What do you think?

Ok heres the deal, i need some advice for my future plans on my truck....its a 1970 chevrolet c/10 with the 350 and a 3 speed....engine is bored .30 over, new 427 casting heads, new cam from previous owner, new carb, new headman headers, stock 3.73 differential, everything has been rebuilt from the previous owner...i'm guessing this truck has around 250 hp. I want to do a new top end: new hydraulic roller cam, new edelbrock alluminum heads, a new intake, and either 2 3/4 in headers or 3 inch headers long tube...ive been told that this will put me at 350hp MINIMUM and possibly up to 400-425 hp. Does anyone have any similiar experience to this and if so what were the results, if not what do u think? Thanx...
