Don't know. What plug does Holley recommend for the heads? I can cross reference them.

**swervin ervin** · 03-16-2004, 04:11 PM

NGK stock number is 7382, plug number is R5671A-9.

ocbaud · 03-16-2004, 04:14 PM

ocbaud · 03-16-2004, 08:42 PM

i'm not paying 10 bucks a plug

71-longbed · 03-16-2004, 09:21 PM

ngk's are usually about 1.50 apiece ... autolites about 99 cents

ocbaud · 03-16-2004, 09:32 PM

thats a good price

toytruck · 03-16-2004, 11:34 PM

I run NGK R5671A-7 with my Dart Pro1's. Best plug out there.

cochran63 · 03-17-2004, 10:41 PM

with my darts i run autolites and they seem to perform better than the other brands i have tried.

Tom · 03-17-2004, 10:55 PM

BEST plugs? Denso iridium's. Proven 1-3hp gain over stock good condition plugs on our v6 hondas. 1-2mpg better too. Are they worth it? No. A/C delco's are the way to go IMO.

*1FaastC10* · 03-17-2004, 11:06 PM

Tom, the Denso Iridium plugs may be great in the Hondas, i'll give them that. i sold quite a few of them when i was slinging parts, and the guys working on newer imports loved them. however, there are a few things you have to take into consideration... the techniology that Eric is using in his truck. the induction system isnt your typical import multi point fuel injection, with high fuel pressure. he's running a carb, and around 9psi at most. another thing is the ignition system, yes he's using MSD if i remember correctly (which is probably the best ignition manufacturer on the market, hands down) but its a far cry from the coil over plug setups common in today's cars. its not uncommon for factory cars to put out 80,00-100,000 volts, vs the 60,000 or so that Eric will be running. i'd go with a platinum plug if i wanted to go with anything other than the standard style plugs.

79BIG10 · 03-18-2004, 09:07 AM

NGK here as well

chevyfan420 · 03-18-2004, 11:41 AM

A/C Delco!!!

Genuine GM parts for my genuine GM truck

I think split and triple fire plugs are a joke is it true? You would need two on each end of teh spark to make a difference right? Also isn't it your coil giving you a stronger spark?

78' Silverado · 03-18-2004, 05:17 PM

A/C Delco. I have always used them.
