Need Plug and Wire Recommendation:

[74bigblock]

Hey everyone,

Well, I'm really getting antsy waiting for the weather to break. So I decided that in the mean time, I could order up some new plugs and wires, and get that going.

Here's what I have:
454 LS-4 motor
HEI Distrib.
Hooker Sidemount Headers

My thoughts:

I need new plugs that will handle the HEI voltage well, and I need wires that will transver that voltage well, along with good heat resistance, as those headers get HOT HOT HOT!!!

My questions:

What do you think I should go with (Brands)? What size plugs to I need? What gap should the plugs be?

Thanks!

-Dave

Stock type plugs, stock gap. Choose whichever manufacturer strikes your fancy, they're all the same. Everything else is marketing BS and will make no difference.

:eek Why you little _____ !! .... It's only a truck motor if it came from a truck. This is a CORVETTE motor!!

I went with the MSD Heli-Core wires. I bought the universal and routed them over the top of the engine rather than underneath.

You mean you don't have a BB truck motor in your car. :cry

Do Not get solid core Nor graphite core wires. Simply ensure it's 8mm to 9mm, spiral or helical wound wire for BBC w/ HEI. Taylor, Moroso, Accel and MSD are good wire brands. You might like the way Taylor forms their plug boots ... they're easier grasp w/fingers. If your plugs have been about right, then go with them gapped at about 0.045" for HEI. I like simple plain old nuthin' fancy plug designs ... I like Bosch, Autolite and ND (nippon denso) plug brands.

Thanks Jack! I agree with your synopsis of keeping it simple. I wouldn't want to do a dual or quad tipped plug. I've got Taylor wires in my Trans Am... I think I will go that route.

I have heard nothing but good things about Taylor or MSD. I think those are the best around even though they are a little expensive, but you pay for the best.

Anybody have any comments on the 'repro' GM Packard wires one way or the other? Or the ACDelco service replacement wires?

OK I need more help... I've been talking with lots of people, and they have brought up even more questions for me.

-How do I determine what heat range I need in a plug?

-Are there any "plug application guides" I can use? I haven't found any.

Thanks!
