360 Intake on a 318 - What To Expect?

intake port must be smaller or the same size as the port in the head. never bigger. This should never be a question asked if you know of the difference. You can do this when though water flows up hill . I have seen this asked on here many times . You would be in the same boat if you were to get a 4bbl to a 2bbl. adapter and keep your 2bbl intake. Unless you find a intake with the same port size as a 318 head. your decreasing milage and performance. A good choice if you could find em 1. edelbrock LD4B. and 2. 273 hipo. all the rest are multi purpose but they do look look nice?
