ok fellas, had the initial timing set, but the mechanic guy told me that the advance is no good(i guess ill take his word for it, i figure if he drives a chevelle he should know bout stuff like that), the thing is, i can order one from the auto parts for about 20 bucks, but the local speed shop can get me an adjustable one for 30, which one should i go for? thanks for any imput Vic
