Neal thanks for your help today with the p5 break in... If any body is searching this thread for an engine ... Hands down the best customer service I have ever enquired. Not only does Neal stands behind his work . He truly does want you to get the most out of your clocked engine. Was patient and informative through the frustrations of getting that Nova to turn over.. Even walked me through my linkage set up corrections and needle settings. My hat goes off to you sir. Thanks for all your help Neal. Charlie of York Pa
