AMC Engine Help
I have a 1968 AMC Javelin with the original 343 engine. The only changes made to the engine is the heads were ported,larger cam, aluminum intake. This engine stock was supposed to be timed with a setting of 0 degrees, (TDC). The car has never idled correctly since it was purchased. I have spoken with Edelbrock about the gasket set up for the intake to no avail. There is still a vacuum leak somewhere. Has anyone ever ran across this? I know AMC is a lost breed but this little car is a blast when it works right. I have tried Right Stuff, Permatex silicone and still it seams to have a vacuum leak. Any ideas on timing with a bigger cam? It is a 520 lift hydraulic, nothing special. Just been working on this for some time and it is about to get sold. Any help would be greatly appreciated. Thanks. Cliff.
