Anyone ever try this. Doing top end work to my stock 81 Cordoba with a 318 (still has lean burn that works well believe it or not). The cast iron intake is so ugly and heavy, I thought I would see if anyone tried using a 4 barrel intake (looking at the 2176 performer intake from Edelbrock that has the smaller ports) and an adapter plate to adapt the factory 2 barrel to it. Not doing any hop ups on this motor now just maintenance. It's the wife's cruiser and just keeping it going for now. Just don't want to cause any issues by swapping (maybe I would lose some mid range power from what I heard). Do not want to lose the lean burn now or drop a 4 barrel on a stock 2 barrel car. I did notice that the factory intake has the back water ports blocked off. The only mods the car has is removing the smog pump and it has true duals (2 1/4) with no cats. Thanks guys!
