Or detonation!!!!!!!!!!!!

What is your initial timing set at?

Thanks for your replies. I will check on the timing. I know it hasn't been adjusted since I've owned the car (5 years).

Regarding the Exhaust Leak, I wanted to be clear on what under load meant(accelerating, or revving?) The engine doesn't make the noise when revving only when accelerating. The noise is something I've been noticing for a year or two and it has gradually gotten worse, and now it seems to be affecting performance.

Is there an easy way to check for leaks?

Once again thanks for all the help!

pull your e-brake, put it in 1st gear and put a load on it, see if you can stay stationary, have someone stand off to the side with the hood open, listen for the exhaust tick, just be careful, we all know the e-brake wont hold a stang to well.
If it is losing alot of power, then it does sound like detonation, good luck
