Re: New Spark Setup! Any tips on Installation?
If you are using a 4 bbl carb, you can use the spacer off of an 88 to 95 chevy pick up. Located between air cleaner and throttle body. Most gm trucks around this vintage with v-8 or 4.3 v-6 used this spacer, if it was fuel injected. Also includes astro van, and full size van as well as s-10 with 4.3. Holly 500 2 bbl uses same size air horn as 4 bbl
