Bruce, that air cleaner is a 10 buck swap meet item including The K&N filter element.You got one inexpensive engine lol. Other than seeing trucks or cars at the few meets I attend in the summer, have never seen another modified old Chevy or GMC 6 on the road.I had the pleasure recently of showing my trucks tail light to a 48 Ferd coupe with a built flathead V-8.He claimed It was unfair because my engine has overhead valves.Before the "race" he was saying how easily his car could beat my truck with his Merc flattie equiped with all sorts of speed equipment. He had a sour look on his face when he realized his pretty engine made less than the maybe 180 HP my engine has.
