I got my car running and It idles fine but when you give it throttle the cylinder head makes a hollow thumping noise....
I just installed bc 272's and did arp's along with the timing belt, ect....
I don't know what this is.. Is my head shot?? It still idles fine and runs good. It just makes an anoying noise and gets louder as the rpm's go up..
Any help on this would be great... I'm so depressed about it
