Vortec Heads...which spark plugs?

[Derek1387]

been running the Accel U groove plugs.. not happy. They are all black and nasty.

Time for new ones...

what does everyone reccomend????

[slicpartna]

i use ngk

[S/C Z71]

NGK or ACDelco only.

[daved931]

AC Delco.

[Derek1387]

just the cheap NGK plugs?

[richardcerritos]

e3 spark plugs, I also use taylor 409's spark plug cables. I'm happy with them.

[Derek1387]

not a fan of E3's...heard way too much bad about em.

[YenkoST]

NGKs or AC Delco.

NGK on a stock engine would be a TR55.

[bored&stroked]

a/c delco R44LTS in the 98 and R42LTS in the stroker

[Fast305]

a/c delco R44LTS in the 98 and R42LTS in the stroker

R42LTS are the way to go, IMO. 42s are too hot. I ran the R42LTs in the 059 vortecs on the 305 TPI in my van. Ask OldRed95 about running the TBI short reach R43TS plugs in his Vortec head 350. The thing popped, spit, and died out at low rpm because the plug gap was sitting recessed into the head.

[GIMECHANIC_454]

AC Delco or bosch platnum 2 or 4's i had a set of the platnum 2's in my truck a while ago and they worked good i noticed a noticable jump in preformance and about 2 mpg better gas milelage, when i get back to germany I got a set of bosch platnum 4's waitin to go in and the accel plug wires ill have to let ya know how they do, right not i have a set of the AC delco platnums in there there not bad but i think i need to go with 1 or 2 more higher heat ranges

[Derek1387]

so, i found out today about everyting internal on my motor that was said to be done, really wasnt... such as vortec heads, roller rockers, roller cam... everything...

So, now its time to build a new motor.

[Derek1387]

[bored&stroked]

I won't run 42's in my stock 98 5.7, too cold. And Im in AZ heat with 115* days being nothing new and running 87 octane.

[93ChevyTBI]

agreed, i did the same thing.
have you ever refunded the money or shipped the parts (tbi) to 94k1500blazer? I find it real damn shameful on here that you would even communicate anything to anybody until you take care of this?
Supposedly, you wouldn't leave your FSC brothers under the bridge. Care to shed some light on this?

[XLR8N]

He's a P.O.S.

[Derek1387]

....ok then...

Guys pick another thread to do this in...off topic...not in a technical advice thread.

And that is blazer's battle with TBI-Max...not yours anyway.

well, you're right. But dammit it's gotta bother you too knowing someone on here tries to be all buddy buddy with everyone when he's prolly just planning his next scheme to screw someone else.

end of rant....well, maybe...for now. :aniteef:

They maybe too cold in your stock 5.7, but the stock plugs were too hot in mine. 1997 G1500 Express with some bolt-ons.

I know it is off-topic, But if it were you I bet you would acknowledge him when he posted if he avoided your calls and emails. Whatever.

what did it take for you to figure that out? that sucks.

[Derek1387]

took the valve covers off to put on some new covers. No rolelr rockers, factory regular heads... nothing special.

Ended up buying some 42LTS's... so we will see how they do...

unless anyone has anything else to say before i bolt em in.

[YenkoST]

If its not vortec heads, then you need a different plug. Have you confirmed that yet?

[Tbi-MAX]

well, you're right. But dammit it's gotta bother you too knowing someone on here tries to be all buddy buddy with everyone when he's prolly just planning his next scheme to screw someone else.
