i sold him that predator carb. its the race version and we bolted it on to test it out.thats why we ran the engine.
the sound is partly an exhaust and partly a cam. he makes his own exhaust headers and ypipes. he also runs a crazy agressive cam with 11:1 compression so its a little lumpy at idle as you can imagine!
hey if anyone doubted that harbor freight tubing bender, his headers are testiment to their usefullness.
