Put new plugs in

[GTOreturns]

Plugs, wires, cap & rotor.
The gap on the old plugs was .082! That splains the pinging!

Nope, stock motor craft. Now put down the "Rice HP Guide", and walk away from the table....

I always use factory crap. Yes, that is the correct gap. I haven't changed them in 2 years and they were totally worn out! (.082)

Sorry to post jack, but what is factory gap recommendation, & what is a good gap to run with Autolite 3924's with a 300+hp HCI motor?

 

[GTOreturns]

The factory gaped them, and recommends .054

Hmmm. So should you run a factory gap with HCI?

hah you mean to tell me you don't want an extra 160hp?!!?

you could gap them a little smaller but the factory recommended gap works fine. anywhere between .048-.054 works. i think i have mine at .049 or somewhere around there.

Not that I noticed, car runs fine, I was just curious. I just through in new plugs, wires, cap & rotor, 255lph pump, 24lb injectors, & 76mm C&L maf. Fuel pressure is set at 38lbs, but can't remember the timing, but I know it wasn't too much, maybe 14 degrees give or take?

FWIW Dustin, right before I got rid of my coupe I put in some Autolite 3924 and gapped them to the factory recommended .054 and the car ran great with my h/c/i.

Mine are gaped at .028

 

[cenok is family]

lol i think it's a little different for forced induction cars

Autolite 23s gapped to .35 ftw.

It's weird, an engine builder I know swears NO MORE then .035!
