I found this under the dash, I think it's something like the ignition module (sp?) or something like that because the wires goes from the box, through the firewall. Here are some pics:

yeah its ESC, my 84 had it. Electronic Spark Control. It looks for knocks on the knock sensor and retards the timing accordingly. I eliminated it. There was one wire from the computer to the distributor, if that wire was not connected the engine would not get spark. A new distributor and that was fixed(had one sitting that was perfectly fine).
I have an ESC distributor in the cabinet. Is there a way to eliminate that from the distributor so that it can be used without the computer. I never looked at it much so I don't know how integrated that stuff is in there.

I'm not certain. A non ESC distributor may do it but I can't remember it may not go in(internal electronics might not mate up).

You need an HEI off of a earlier year chevrolet. They won't have the ESC connection. Stick that in and dump the computer.

Does it have to be a factory one off an old chevy, or can it be something like this? web page or what? Also, if I wanted to run a MSD distributor (or something simular in quality) will that need the ESC computer? Sorry, I dont really understand this to well...

aftermarket distributor won't use ESC unless its exactly as factory design(Mallory or MSD won't be). You could use that Mallory dist. but I'd say its a waste of money. A stock GM distributor with adjustable vaccum advance(cheap and you don't need it) and an upgraded coil($30) would be about the same damn thing. Only reason I'd buy a nice brand new distributor would be a high performance application even then I'd probably build my own(buy parts and put it together).
See what you can find a distributor for. Depending on what you find one for go from there as far as upgrades are concerned and see which is the better value.
At autozone an accel cap and rotor kit is like $26. Add a nice MSD coil for like $40 and you've got $66 into a distributor + the cost of the unit itself.

oh so I shouldn't waste my money on an aftermarket one? Whatever engine I have in the future, I was going to get it ebuilt, etc and put new parts on, so I thought I could replace the distributor to, but I guess not.
Thanks!
Thanks!

depends on what you get the distributor for. Much more than say $20 or 30 buying a new one makes alright sense. Its already "rebuilt" and has the parts you would need anyway. For me it makes no sense, I have a stash of distributors at hand.

what makes no sense to you? Buying a new one. Do you have a stash distributors you got from the junkyard for spares or something?

yes yes and yes
free not from junkyard. Dad used to own a tow truck and hauled junk cars. Whats fun about junking cars is, sometimes people pay you to do it, you can scavenge them for free parts, then junk them and get paid /forums/images/graemlins/wink.gif. Too bad insurance on a Tow truck is insane unless you use it all the time.

Okay I guess I will just scavange the junk yards, or maybe your house /forums/images/graemlins/ignore.gif if the Distributor on the engine is dead.
Thanks
Thanks
