Hello,

I am new to site and hoping all of you experts can help me. I recently purchased ( 35 miles ) Superformance Daytona coupe mated with 427 Roush and Tremac 6 speed tranny. Upon acceleration (medium) this loud short KNOCK comes from which sounds like engine to transmission area but I do not think it is internal. I spoke to the installer and he said this is normal caused by the sound echo ? Sound familiar -- I am somewhat concerned before I have fun. Thanks
