I took a 406301 exhaust manifold off my 70 442 with 455. I know its wrong for my car but would like to know what it may have been on origionally.
Any help would be great!
Thanks
Gary

I've found these on 1971-72 Olds 98, not sure if there's other years or applications that it would be correct for. John

 

8thanks so much John

406301 X manifold should be 1971-72 full size. These are not internally divided and thus do not flow as well as the 402295 W manifolds. Do not confuse this with the 412287 X manifold that IS internally divided.

 

Thanks Joe.


I have an extra one of these in excellent shape if you know anyone needing it.


Thanks again
