Under the index for under a grand!

I finally took the time to "back-to-back" sparkplugs on Saturday and I was a bit suprised at my findings. When I put the car together, I put in the least expensive plugs that W-Mart had. Just basic plugs. I did an A-B-A-B test between them and a set of iridium plugs that I have used in some of my other stuff. So can a $16 set of plugs perform as well as a set of $64 plugs? Not quite, the iridium plugs averaged .034 ET. and .3 MPH faster than a basic plug. Are they worth the extra $48? In a heads-up or qualifying situation I guess they are. You decide.
I also took my junk-yard headers off and put on a set of mine and found !!!!!!!!!! that I really have to do some carburetor work to get my stuff to work on this car. The car went the same ET. and over .5 MPH faster but it wasn't happy leaving the line.
Another job for another day!
