I have two sets of y-block, dual exhaust manifolds. I wanted to use one of them on a 61 uni with a 292 ,and was wondering what info you can give me on them,if any.The steering box will not be an issue.
the first set is ECH-9430-A,and ECH-9431-A.
They are fairly thin in stature and it appears they point directly behind the clutch z bar, but have heard they can be swaped side for side so the exhaust can be routed from the front of the motor, to avoid any potential problem.
I just bought a great set from Charlie Burns,
this second set is B9AE-9430-A and EDB-9431-B.
There is a big difference in part numbers. I believe they would provide much better flow
These are flat topped, much fatter in stature,but there appears to be little other difference in shape or stance to the first set. I believe these can be swapped side for side as well.
Could anyone give me any info on these. I really dont want to put in headers.
