what spark plugs do i use in these heads ,,,,,on a 400ci sbc with a 750 vacx holley and a 2116 edelbrock,,,,,,i notice the spark plugsare longer than normal sbc,s,,i do prefure ngk or bosche,,,,but champion part numbers will do for a cross reference,,please asap ,,i am 12000 miles away

 

Just go to a parts counter and ask them for spark plugs for any late model truck with a 350, knowing for sure that it has vortecs ofcourse. Like 96-2000

people here dont drive them things,,,its toyota landcruiser ,s here unfortunatly,,,,,,,not mony late model chev trucks here

 

I'm sure that they'd be able to at least get you the part number, if not the plug itself.

i tried a few today,,these places are run by kids,,,when i mention 350 chev truck 1996and up there eyes roll back in their heads like the are on Lsd,,,they have no idea,,what a 69 camaro looks like ,,let alone a 1996 truck,,these dudes are into 4 cyl **** burners,,sorry

 

Vortecs use a Champion RS12yc

 

ask for vortec truck sparkplugs and youll get very $$$$ platinum ones :-)...... I cant remem the number for sure i run on mine, but any GM Peformance parts catalog has the plug specs listed with the engines and they are several vortec headed ones available so thats a great starting point...

Also do a "search" and we wouldnt be here right now :-)

U will find the correct plug numbers for vortecs heads there too
