I was wondering if I can take out my old manifold with a 1 barrell and buy a manifold with a 4 barrel or a 2 barrel opening..if so where can I get this.?
chack out www.classicinlines.com you will find a wealth of performance info for your six. That is where my christmas list is based from!! (christmas 2025 probably!!)
the intake manifold it directly casted into the head so your going to need some mechene work to get a biger carb hole cut into the head, or run an adapter plate theres pretty much no way a 6 thats anywhere close to stock and not boosted would ever need a 4bbl carb a 2bbl with an adapter plate is a nice addition to most 6's though a h/w 5200 or a holley 2300 are very popular
