i dunno what type of distributor i have but i was told it was a non HEI since i have a small cap. i need to buy spark plug wires for my car(custom kit) because i got headers. but if i dont have an HEI can i use HEI wire kit? what would the difference be? they look right have all the correct boots and everything theyre just a lot thicker. thanks in advance for any help

im not sure if HEI large cap wires will fit on the FI small cap towers or not but the only (visual)difference that ive noticed between these two wires is that the HEI large cap ones have the ring on them for the retainer deal that pops on over all the wires


dunno otherwise

diameter of the towers and length of them would make or break this

but then you could just swap boots on the wires,



good luck

Both the large and small HEI caps use spark plug type terminals. Older points distributors used a socket style terminal.

so i can use HEI wires on my non HEI i think it is distributor? BTW its a custom cut to fit kit by MSD.

Your distributor, if it's stock or a stock replacement, is HEI. To tell, just pull a plug wire off the cap and look. If the terminal on the cap looks like the terminal on a spark plug, you need HEI terminals on your wires.

o ok thanks a lot i was being told it was non-HEI. at least i got the right wires for it then by MSD. thanks a lot guys
