Did Buick have an 4 barrel intake for the 1966 300 (307)engine? If not, is there one available after market? Just trying for better gas mileage, not speed.

Buick did make a 4v application for the 300. I would reccomend contacting Ken and Sue at Wheatbelt Buick in Carrier, OK. The phone no is as follows: (580)-855-249 or you can find them on the web at: www.wheatbeltbuick.com. (http://www.wheatbeltbuick.com.) They have been a great source for parts for me over the last few years. If they don't have one I'll see if I can't come up with one here in KS

Thanks , Aaron. We are leaving to visit our daughter, but I will contact Wheatland as soon as we return. I appreciate your fast reply.
