I don't believe your going to get another 100 HP with out doing some major machining and buying expensive parts, unless you add a power adder, like a turbo, blower, or the juice. A bigger cam, intake, carb & good heads may bring you say, 50-75 HP. or closer but, I doubt 100. If you really want 100 +, I would recommend saving some money & do it right from the get-go. You can achieve 450-500 hp with apx. $4,000-$5,000 for machining & parts. A lot of that is in the heads. You can get real crazy there.
