not a fan of E3's...heard way too much bad about em.
NGKs or AC Delco.
NGK on a stock engine would be a TR55.

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.Originally Posted by bored&stroked

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

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.
agreed, i did the same thing.
so, 42lts are the way to go?
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.

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?
