Re: Exhaust Leak?
I don't think it has anything to do with exhaust, when did it start doing it, are you EFI or carb'd? Did the crate motor come with injectors and plugs, double check you are using the right plugs and make sure all injectors are firing properly, may sound wierd but you could be running lean on one side of the motor, it will pop between shifts....I could be wrong...
