| 454 chevy timing
Hello, We are new to the forum and new to the Airstream Motor Home. We have had the 90- 345 LE for about three weeks now. I am in the process of tuning it up now and am trying to check the timing on it but that does not apear to be as easy as it is on my 51 Mecury with a flathead in it. We have the 454 chevy with the banks power pack. I cant get to the timing mark from the top, is there a beter way to approach timing of this motor
