Q:
Are these manifolds manufactured in U.S.A.?
A:
These parts are manufactured in Taiwan.


Q:
I notice these manifolds only have one Bolt per port. Doesn't seem enough for a good seal. 5.8l Ford 1991?
A:
Well this particular manifold can be used for the port or starboard side and it comes with the mounting kit which contains four bolts. This fits: Ford 302 and 351 CID engines, Crusader 302 and 351 CID engines, Interceptor 221, 260, and 289 cid engines, Commander, Mercury, OMC, Palmer, Pleasurecraft & Waukesha.


Q:
Will it fit on a 327F 1968 chris craft marine?
A:
We do not have a manifold that will work for that engine unfortunately. You will need to contact Chris Craft.
