I have a 65 C10 that I'm building a 350 sb for. I would like to have about 300-350hp. It was recommended from a friend that I find a stock motor in this range and use the same parts the factory used. I've gone as far as to purchase a 75' 350 4 bolt and a set of 68' double hump heads. I had the heads changed from 1.94's to 2.02's. I was thinking of using an Edelbrock Performer intake and an Edelbrock 600 manual choke. I don't know where to find the specs on the best pistons and cam to use.
