It’s a factory 4 barrel. A 1958 318 poly intake. No, I don’t have a factory carb. I got the intake off a FBBO and it came with an old school aluminum adapter plate from Cal customs. But it was cracked and I managed to drop it and bust it completely. All my research shows that they used two different carb options back then, a Carter AFB style and a Carter WCFB style carb. Neither of which I can find an adapter that actually bolts to this thing, despite what the adapter claims to fit, and then to a Holley carb. Which is what I have.
