My understanding is the 2176 manifold is tapered to suit 318 size heads but can easily be ported out to 360 port size?! I have one here I can feel the taper. For a car that's not a race car I'd just port match the 2176.
HEY!, watch it now.
What am I going to do for an excuse to get a new intake if I do that? :D
That was what I was thinking though, since it runs just fine for everything I do with it.
It's a daily driver that takes long road trips on occasion.
Thanks.
