haha well, I don't THINK there were flames; but I don't know because the hood was down and air cleaner was on.

However... you guys are making me wonder. I have a speed demon carb, which is similar to a Holley. The garage always smells of gas after I park the car so I wonder if I have a leak too, I just assumed the gas smell was because the carburator system is a wet fuel system so there would be fuel in the intake. If I have a leak, that may have been what caused the detonation.

I still want to check compression to make sure I don't have a valve that is stuck or a broken timing chain. After that I will turn her over with power and see what happens.
