If you want to go one step further a good set of low resistance plug wire an help too... I think it was recommended to have them below 1000 ohms of resistance... I bought a make you own set from Msd, I believe, I bought a V8 kit so I have extra wires if needed... i can find the part number if you like.... 1 Quote Link to comment

Crashtd420 Posted November 29, 2020 Report Share Posted November 29, 2020 Did you ever catch the info on counterfeit plugs.... Definitely buy from a reputable source... 1 Quote Link to comment
Zonargx Posted November 29, 2020 Author Report Share Posted November 29, 2020 (edited) I’ll look into the wires also but so it’s best I get b6es over the BP6ES . My pistons aren't flat and I bought the plugs from autozone right around the corner from my place Edited November 29, 2020 by Zonargx 2 Quote Link to comment
datzenmike Posted November 29, 2020 Report Share Posted November 29, 2020 My 710 is BP6ES and '78 620 was BPR6ES. This is for an L20B. Both are projection. Projection plugs run hotter thus better self cleaning at lower speeds. At higher speeds they are cooled by the inrush of air and fuel. They are closer to the center of the combustion so the flame has a shorter radius distance to travel out to the edges than if the plug was on one side and it had to travel the diameter distance. Shorter burn time means the ignition can be retarded. 2 Quote Link to comment

I did have to open up the clip on top of the valve cover a little... Comes with the crimp tool too... 1 Quote Link to comment
Zonargx Posted November 29, 2020 Author Report Share Posted November 29, 2020 I place the order on the plugs already. Going to install my alternator bracket now. Thanks for for the help guys 2 Quote Link to comment
Zonargx Posted December 1, 2020 Author Report Share Posted December 1, 2020 @mainer311 I believe I saw some pics of your sound system set up a while back I believe it was a topic of the carpeting re done? Didn’t you have some mids installed on your door panels? I want to install some.... all I have right now are some 3 inch teeter from when I had my old 73 Chevy c20 but I want my mids. I’m sound dampening my truck in a few days probably Saturday or anyone else have how to install ideas or that they've done ? Quote Link to comment
mainer311 Posted December 1, 2020 Report Share Posted December 1, 2020 Yes, there are 6-1/2” in the doors. They are 2-ways, with a directional tweeter in the center. The previous owner cut the holes to mount 5-1/4”, but I managed to get 6-1/2 to fit. It’s very tight. The window crank gear rack comes down and is very close to where he cut the holes. If I had done it my way, I would have built a custom center console that fits over the transmission hump, and had 2 angled speakers in that. I may still do it this way if I ever get replacement door cards. Quote Link to comment
d.p Posted December 1, 2020 Report Share Posted December 1, 2020 I thought about speakers but in the end I just use a JBL flip 4 which hits hard enough for me. 1 Quote Link to comment

Or better yet get something larger like 8" 'subs' for the custom enclosure and again move the hi range choice farther apart. Low frequency sound is non directional, you can mount anywhere even under the seat. High frequency needs to be farther apart to fool your ears with the illusion you're in a larger room. I have a pair of what used to be called 'biscuit' tweeters. Like a small cookie sitting on the dash on each side facing up. The high frequency sound projects upward and reflects off the inner windshield producing the illusion of a larger room. Mid range speakers are more in the 6 1/2" range so leave in the doors or as far apart as available. 2 Quote Link to comment

Think about it: the driver's side door speaker is firing into your leg and bouncing off the wall on the other side of the cab. Your head is completely out of the zone that the mid-woofer is projecting to. Not to mention...this is a 521, not a bus. Then again, I don't know much about audio.

True that. LOTS of snake oil. Just like after market 'performance' parts. Technically 'better' but truly not worth $50 a HP. Quote Link to comment

banzai510(hainz) Posted December 1, 2020 Report Share Posted December 1, 2020 we use Fliukes at work also. I found a Fuke 70 at the Pawn shop and got it at home. But I also have a old Simpson analog also and a Tripplett analog. Don't pop the Fuse!!!!!!!!!!!!!! Quote Link to comment

They should be able to get them no problem, are you asking for the plugs for you truck or asking them for the specific plug..... I actually dont see them available through autozone, they have the -11 but not the regular b6es, but it seems like napa, advance auto, and oriellys have them... 1 Quote Link to comment
Zonargx Posted December 2, 2020 Author Report Share Posted December 2, 2020 Yea I was already able to get a hold of some from Napa and they will probably be ready tomorrow. Oriellys couldn’t find them either. Napa has them it was $15 just to deliver home haha that’s more than a set of plugs so I’m just picking up Quote Link to comment
