Hey!
Does anyone have experience with getting wire sets for a 351m?
dont really care about money, just want to know what would work good paired with
XP25 autolite plugs

Thanks!

I’ve never found a good set that had the right lengths so I’ve alway bough universal sets or just bulk spark plug wire and made my own. If you have a stock ignition you won’t need any big fancy type wire either
