As a few of you have read a while ago,I thought I was having cam problems.Poppety pop pop out the exhaust.A friend of mine found an older thread talking about vortech heads on a monte carlo forum.It stated that vortech's are actually different than the older small block heads.They said to get plugs for a'96-up engine,and not the shortie plugs.So...I DID!What a difference it made!Ya know it's amazing what can happen when you put the fire where it belongs!It even runs WAY better than before I had the problems.Lays rubber at the drop of a hat,even with the 2.41 gears :cool: In thespring I plan on putting better gears in,and a nice beefy cam as planned.Thought I'd spread some good news...for once,and possibly food for thought to some out there.Later elky lovers!

I have Edlebrock vortec heads on my 383ci small block. I can't seem to get it to run 100%, but I assume it is a carbueration problem. I will have to look into the plugs I am using. I have Autolight 103's in it now, i will have to reference what they are designed for. Good info! -Matt

It'll definetly wake it up! I thought the same thing then it got worse thinking it was the cam.When i took it for a spin the response I noticed is practically immediate.It's gonna be worth your while to check into this,you'll be glad you did!....trust me 8) good luck!

Hey Matt keep me posted on your find....I'm running the same Autolite 103's also....Dave

Dave, I found that 96 camaro z-28 uses Autolite 106 plugs. I think they are the same plug just a different temp rating. So far the 103's look to be the correct plug.

did you crossreference the plugs at all? any kind of plug for a '96-up is different than because its longer than the older style small block head.the vortechs are actually different they have different runners and chambers.i also compared plugs between the ones i was using and the correct one,and they are about a quarter to half an inch longer at the firing end,also a little taller too.the firing end was too far from the center of fire.not to sound too opinionated but i had alot of bad luck with autolites,but thats me.good luck

not to sound too opinionated but...

You, opinionated...never! :P :mrgreen:

Member "neverdone82" is the one who brought this info to our attention. I made a great improvement in elcaminokid's (Rob's) Elky! Gotta do mine now!

i have a set of vortec heads off of an 88-89 350. would those bolt to my '70 350 i have in the elcamino right now? if the will would they make any kind of difference in performance?

Ben, the Vortecs you want are the '96 & up model years. Thats when the "performance" changes were made.
