Hi All, I have found For A Bodies Only to be a great wealth of knowledge and it has helped me out immensely with my 1970 Dart Swinger 340. I finally decided to join!

So what I am trying to get some help with is cam identification(if even possible)

The paperwork that came with my Car regarding the engine is very vague and I have been trying to identify the cam. The following was written on a piece of paper.

Cam= Hydraulic H. Performance (Purple Bigger)

Compression ratio=10.5 to 1

Heads= Comp. valves porting

Does this information help at all with identifying cam or getting close?
Also if not, aside from opening up engine, any non-invasive ways to figure this out?

Thanks!
 
Not even in the ballfield. My apologies.
 
Sorry to say, but to positivity ID the cam, you need to take down the entire front of the engine and read the numbers in the snout. If it is there and not on the cams butt end which would require the cam to be removed.

You can get a good read on the cam without all of that if you have the tools to degree the cam. This way you can write down the timing events @.050 and where and when everything happens.

It’s a catch 22. Your call.
Or get a new cam!
:lol:
 
Or who cares what cam is in there. Does it run good? Does it ping? Run it and have fun. Cam specs can be helpful for tuning but not necessary.

You could take the driver's valve cover off and bolt a degree wheel to the vibration damper and degree it in the car to see what it is...

That's the only reliable way to know for sure...
 
Thanks all for the info. I actually have it tuned pretty good and runs strong. It was more a curiosity thing because someone took the time to right that info down that meant nothing to me and took a shot that someone may have some insight. But toolmanmike has is right. Doesn’t matter, runs great and no pinging. Thanks again guys!
