I ran these on my truck for a few years and they worked very nicely. Gave the truck a noticeable difference in power and performance. I just had them Sand blasted so what you see in the pic is bare metal. I will be adding a coat of primer just to prevent any rust. The part# is 6863. Edelbrock's website says it fit's 81-86, but I am sure it would fit other years also. $140+shipping. Box weighs 25lbs coming form 93312 area code. I prefer Paypal but a MO will work too.
