If the engine is a turbo engine and had a two barrel carb it's a relative rare engine. You can make the swaps but you should consider the cam also. The turbo engine didn't need the valves open as much as it was force fed. To get more horse power you need to reconsider the air intake of the thing. Cheaper to do a little hood mods and have a real cool engine that will carry the car down the road as good or better than the redone one.
