“ That isn’t even close to a stock idle”. The plot thickens, what cam do I have? I wouldn’t want a milder cam, takes the fun away. Maybe, I should just change the noisy lifters and leave the cam alone. Car has very good power, runs good but, it always had slight lifter noise. There is info on Chuck Melton’s Pantera Place website where he successfully changed the lifters w/o changing the cam.
I have a solid lifter Comp Cams presently installed. It is a 294s grind.
Yours sounds a lot like it.
This is the generic sound bite from Comp Cams for that series, but listen to this. You can hear the similarities.http://www.compcams.com/Base/M...ytes/CompCams292.mp3
I can't tell from the video if your cam is solid or hydraulic lifters.
I will say that very hot hydraulic lifter cams with triple valve springs and anti-pump up lifters sound very much like solid lifter cams. The anti-pump-up hydraulic lifters click like solid lifters do.
They have a lot of valve train noise.
You should take the car to someone who is familiar with aftermarket cams and preferably with High Performance Ford engines and ask them to "look" at it.
There is little that anyone can do to specifically identify the manufacturer of the cam.
Many have ID numbers stamped or engraved on the face of the first bearing lobe, but you would have to disassemble the front of the engine to see it. Even if you did that, it may not be enough information to positively identify it?
I'm agreeing with ZR1 Pantera. You may have a solid lifter camshaft in there and if so, that valve train noise is probably normal for it.
We agree on something? My God! What is the World coming too? I hope this isn't one of the Seven Signs of The Apocalypse?
Someone who is very knowledgeable on camshafts needs to look at the car in person.
It probably is going to at least mean taking off one of the valve covers to see what that shows.
It should at least identify the type of valve train you have? You could in fact even have a solid roller cam profile in there? They sound similar.
Who did you buy this car from? Didn't you get any engine information on it?
Another observation from the video is that you have a lot of exhaust noise on this car.
On a Pantera with Ansa type mufflers and tube headers, this is absolutely normal.
Even with the stock engine the exhaust is not quiet.
Many people just equate the sound of the exhaust to loud valve train noise.
This could be what is going on here also.
Bottom line is your setup isn't close to stock.
Even the mufflers are louder.
I would also add that if that is a solid lifter engine, the valve train noise is very low, and whoever adjusted the lifters knows what they are doing because they are NICE AND QUIET at the valve covers.
Your engine is also idling around 700 rpm. Mine idles 650 to 700 rpm with the Webers.
The cam I am using, spec'd above, is quite capable of idling at that rpm.
I describe the idle on mine, "like a speed boat". I would describe yours that way as well.
I think you have the same Comp Cams grind that I do.
The biker guys like mine. It sounds a lot like a big bore Harley Davidson. They think it's "bitchin'".
I will also point out that mine is a bit louder with the 3" bore glass pack mufflers on the 180 headers. The cam overlap will knock the cap off of your head if you walk within 20 feet of the back of the car at idle. I hate that.
You probably never thought of your car as "quiet", did you?
Hum? Everything is relative?
