hp..
well..gotta give more info for others to make recommendations to you??....yeah...a 500-500 cfm 4 bbl carb would give you more top end speed...not so much hp....it allows the engine to breath at higher rpms..more efficiently....ie..more gas..more hp..more torque....more rpm speed...if you really want to add some hp..then add a paxton low profile supercharger....but that may cause more hp/torque than your engine can take....
there is always a trade off.....or more directly a cause and effect....if you do this...that may happen....is the engine able to handle another 30-50 hp.....changing the cam profile and adding a 4bble would give the most bang for the buck.....of course being careful to not explode the bottom end.....so it depends on how much you want to get into the engine...if you take it out and tear it down to the basic block...you can go from there with balancing/blue printing the engine.....then porting/polishing the heads to make them breath better.....profiling the cam to meet the rpms.....porting the intakes.....3 angle valve job...and the list goes on and on.......just something to think about... :wink:
