I rarely read your post anymore since I put you on ignore but curiously got the best of me. So Andy picked up 30 horsepower for 2000.00. I’ll show you some testing on different intakes and before and after number. Now before I go to far a good gasket match probably accounts for 70% of the gains. First example will be a Speedmaster that I bought on sale to port and sell. I don’t particularly like dual planes but they have their place.

This is a 325.00 (at the time) job by a millwright turned head porter. How many horsepower should those numbers account for. There is no way in this world could I justify 2000.00 for any street car or bracket car.
