selling my Offenhauser Dual Quad intake. was going to adapt it for a blower,but thought I would offer it for sale and if it sales, buy a blower intake. it is part # 5488. I've already opened up the ports to match the large 340-360 heads.only price reference I could find was at offyparts.com and they get $516.15 for it. I want $300.00 + shipping. clean and ready to install. contact me at firstname.lastname@example.org. I don't hang out on the computer a whole lot. Tom.
