/6 4bll intake.

Price seems fine. I'm not to up on /6 intakes. I also do not know if Offy made more than the 2 intakes I know for the /6. Being 4 bbl. intakes. One standard port, one dual port.
The /6 forum would be your best bet on info and fine help on it.

I remember Offy, making at one time /6 intakes, or at least straight 6 intakes, that had multiple carb set ups. Like 2 - 2bbl.'s or 3 - 2bbl.'s
