I can't speak for anyone else, but I can say that the 0039's in mine are as quiet as most and quieter than some stock motors....

 

I'd like to jump in on this...I did notice an increase in valve train noise but I'm attributing that to the lift of the cam. I believe what I'm hearing is the valve snapping shut. I used HQs EZ intall adjustable pushrods (I think they are from Andrews...but not sure). In the instructions they say to remove all lash from the pushrod (making sure the valves are completely shut) and adjust 3-4 turns. I adjusted to 3 and heard alot of clatter...then to 4 and still have a bit of noise. From what I can see, I believe the lifter plunger is collapsed about 3/8 - 1/2 inch...approx 1/2 of it's travel. Anyone have any thoughts on this?

The additional top end noise doesn't really bother me...but I'm used to driving muscle cars with 500plus hp so the noise isn't a big issue for me.

 

Plus the stiffer springs probably have something to do with the valve closing hard.......making more noise.

I can put up with a bit more noise if I can get 110/110 or more

Steve..... did you score the cams?

 

Not yet, still waiting to hear back from him with pictures. He was taking them out this week and is sending me pics after.

I sent you an email also.
