Just put all new parts in a freshened up 86 model 5.0 for my 94 Cobra. Engine is making a weird noise and it sounds like it is echoing though the intake because it's louder through the upper than through the valve covers. Cars in time, checked pushrod length, checked valve clearance, rockers are right, running constant 50 psi oil pressure, car idles well and drives great, engine is broken in so i made a slight pull and the engine pulled fine until upper rpms it started to sputter and acted like it was hitting a rev limiter. Any help or advice would be appreciated .
