Just a question...how much valve train noise should a mild stroker have? I think I read that they do make a bit of noise.
I am running a Comp 68-231-4 with matching lifters, mopar performance springs, retainers, locks and valves.

Re: Valve train noise...
That Comp Cam does make a bit of noise. Its like almost a flutter sound. Not very loud, but you can head it. Its not like a loud tapping noise though.

Ours makes a sewing machine type sound. It's quiet though and I don't notice it hardly at all.

Re: Valve train noise...
I'd expect yours to make a soft ticking noise at idle due to the fast ramp rates of the cam and the stiffer valve springs, but you shouldn't hear anything while you're driving though.cigarluvr wrote:Just a question...how much valve train noise should a mild stroker have?

Re: Valve train noise...

Re: Valve train noise...
Its not that bad, just a little first engine build jitters. I am hearing the "sewing machine" sounds as well as the flutter. To further exasperate the sound is the hole in the firewall where the accelerator cable goes thru about an 2 inches from the No. 6 header tube. I may be hearing a little more because of that. Off idle, shes throaty as hell, thanks to the combination Homemade ColdAir Intake, Borla header, 2.5in exhaust, and Super 40 flowmaster...

Re: Valve train noise...
A hole into the engine compartment will definitely make it louder. LOL

If you do hear anything while driving it's usually at ~1500rpm.SilverXJ wrote:You will hear something while driving as well

Re: Valve train noise...
I had a little noise with my Crower 44243 cam..... bugged the heck out of me because I was so careful setting the lifter preload at 0.030" on all valves.
I pulled the valve cover, put each cylinder at TDC to check for excessive valve lash or bent pushrods... all was good, so I started t put it back together.
When I turned the valve cover upside down to clean off the gasket, I saw a shiny spot at each end on the baffle.... the baffle was bent down a little and the rockers were hitting it, causing the noise. Fortunately it was an easy fix!
