offenhauser 4bbl 360 intake??

It depends on the model as to how well it will work for your engine. Offenhauser is quality stuff. I had a dual port 360 deg. on a 360 on my '77 pickup with a mild 360. Great for torque. I had a Port O Sonic on a 340 and it was great above 2500 RPM. But hey, for free...snatch it up!
