Need some help with the goose's 302. I've been having a problem with the goose lately, it starts and idles and revs up great but with low vacuum reading (about 10hg, I have a .456 lift/218 duration cam installed). As the engine reaches normal operating temperatures, the idle drops until the engine dies. If I increase the throttle the engine will stay running. It will start right back up but will not idle until cool. I ran a compression test today. Not sure what normal reading should be but they seem low and are not consistent running about 50-75psi. I have to run the compression test again after squirting some oil into the cylinders. If the readings stay the same I am suspecting that I have valve problems. Am I on the right track? I have swapped out 3 different ignition systems and three different carburetors with no change which is why I ran the compression test.
