I'm planning to do a major tune up very very soon.

Ported plenum, air foil, new plugs, wires, cap, rotor, headers, and 02 sensor. Since they are all bascially near each other...


My question is, I don't really understand the ignition stuff very well.

I'd like some Custom fit MSD plug wires. But I'm unsure of the part number. I'm coming up with two different ones depending on if I want 88+ chevy car or 87-91 TPI vette.

Second, what would be a part number for a replacement cap and rotor from MSD. I was looking, but I found a cap that looked like mine, but the rotor was way off.

Also, on the caps which is better (and for what purposes) vented or standard?

Thanks

 

The ones for the '85-'91 vette are what you're looking for. Those are the wires i have on my gta and they fit fine.

 

Thanks, any idea on the cap and rotor?
