Haven't started my new 400 stroker yet and I'm sure the performance of the Firecore wires is among the best. The quality looks good but really disappointed with fit. Yea I know all engines are different but shouldn't it be rather simple to make the wires fit with out hanging all over? I would think they are all fairly standard. Plus it sure looks like the boot on the #5 plug is going to need a shield as close as it's to the header. They are the 2-1/8 SR step header but I would think I'm not the 1st one to use that size. Hate to call him up again as this is my 2cd set already. Whatcha think; am I being too perfectionist (anal)?
