summit racing and a few other places sell clear distributor caps which can be useful1965SS396 said:I've fiddling all week (learning as I go) with my rebuilt 396, mainly with the timing. I'm clearly a novice, but here's what I know:
I can set the timing to 12 or 20, and if I remove the vacuum advance hose there is no change in engine speed or via the timing light reading. Is that normal?
The higher I increase the timing (around 20 or so) it idles higher and runs better but it has a slight miss and is a little jerky when I accelerate. Lowering it down to about 16 or so it runs like crap.
I also have this lifter like tap that disappears when you give it gas, only heard at idle. It also changes with timing adjustments. I can adjust it out via the rocker nuts, but comes back as I play with the timing.
The coil on the hei has a date of 1985. Is it time for a new one? Is this my problem?

yeah I know most of the guys reading this will either skip over or ignore the links and sub links but if you really want to fix that distributor a couple hours reading will do an immense amount of good here , if you were local Id suggest driving over here.
like anything mechanical thats 30 plus years old, it most likely needs to be taken apart, carefully inspected, cleaned oiled, and have a few worn parts replaced to function correctly
