I've made several posts lately about the 383 stroker chevy engine I just had
installed in my Camaro.
Thanks to everyone who has given me advice. The engine has been running
well, I have about 600
miles on it since it was built. I noticed a spark coming from one of the
ignition wires arcing to the header,
turns out the wire was cracked. I just installed a set of Accel header
plugs, to give a little more clearance
between the plug boot and the header, but my question is, what kind
of ignition wires should I buy? Is it worthwhile to buy the more expensive
8.5 or 9mm wires? I don't
mind spending the extra money if it would help the performance of this
PS Would it be worth the $$$ to put in a high performance ignition system?
Those Accell plugs are trash. I wouldn't run them again if you paid me.
They may be short and fit the headers better but they will die behind just
about any ignition. I used to run a complete MSD ignition. I went back to
a stock HEI and I couldn't be happier. Bosch platinums with a stock
ignition last a good while. Accell plugs and an aftermarket ignition will
last about a month if you're lucky.
To answer your question about the larger wires, you don't need them. Get a
set of good replacement wires and call it a day. Route them away from your
headers as best you can. If you keep frying them, buy a set of Taylor wires
that are rated for higher heat.
Accell header plugs were designed for those who use them for one pass, to
take plug readings.
To re-jet the carb(s) to tune the car for every last 100th and mph they can
get. Most definitely not a street plug!
i just bought a set of the accel header plugs for an engine i just built
(327 bored .030, 520 lift custom ground solid cam, eagle rods and crank,
11.5:1 compression, weiand team-g intake, barry grant made holley carb 650
cfm mech secondaries) about 510hp... (well, that's what dyno 2000 is saying
so far, but it goes on a real engine dyno in 2 weeks to be set up and
tuned) - it has cutom made headers and they are tight to the plugs and the
best fitting wires i could get were taylor pros (universal/custom) with 90
degree boots - put plug boot heat shielding on them also and the header
plugs make it just that little bit better of a fit - have yet to try them
out but will let you all know my results - will be running a holley strip
annihilator system with crank trigger ignition.
if the plugs pack it in rather quickly, will be going back to what i use to
run when i raced.... ac delco plugs, never had any probs with those.
I also had AC Delco plugs in this 383 when I first had it rebuilt, but they
were so long, the spark plug boots wouldn't go on a couple of them...
I think I'm going to run these Accel plugs this summer, put on a few
miles, then pull them & see how they hold up...thanks for the input.
A good set of Accel 8.8 Veriboot spark plug wires is the answer.
They come in all standard wire core types. Along with Accel's heat sleaves.
This will help prevent header burn thru.
As long as you have a good Distributor cap with brass contacts, and a
rotor with a good contact, A good after market coil & HEI module should be
all you need for the street.
Ijust tried a set of MSD wires and I couldn't be happier with them. They are
much nicer than the Accel wires they replaced. As for the plugs, I have used
the Accel plugs in the past with good results, but I never used the header
plugs. Accel plugs used to be made by Nippon Denso, and they were nice
