Pinging

This is the second issue with the 1969 GTS.

So far I can not offer a lot of info.

I do know the engine has a solid lifter cam. Owner says 3/4 Isky. He will try contact the guy that built the engine.

It is pretty lopey at idle, but it never stalled on the trip home in heavy traffic and it runs cool.

But oh my the ping. The worst when you get on it and it drops into second. Serious ping.

When I test drove the car I told the owner it pinged. He and his supposedly expert mechanic put it off as my confusing ping with a solid lifter valvetrain noise. Ticks me off cus I told him I know what the hell ping sounds like. But this guy rarely drove the car and I don't think he ever got on it or had it on the highway. Enouugh of the ***** session.

I know some of the questions you guys are going to ask.

What is the compression.
What is the cam.
What carb.
What is timing set at.

I will try to find out asap.

I do have a timing light so I should be able to provide that soon.
The rest may take some time.

But it will help if I can get some direction on this from the pro's as well. I know the basics, just been a long time since I wrenched on a car.
