Fellow listers,
I have a client with a '76 450sl. In an attempt to improve performance
a bit, we are considering installing the tri-Y headers and downpipes
from a 500slc and fabricating a custom exhaust (or modified 500slc
exhaust) for the remainder. Both are m117 motors and as such I believe
the 500slc headers will bolt right up to the heads. Given they are both
107 cars, there should be no issue with steering box clearance. What I
do not know is if there a size difference with the exhaust ports that
needs to be reconciled? Has anyone BTDT? Anything to be wary of? This
car does not need to pass emissions so those issues are moot. FWIW,
this is a former California spec car.
Thank you in advance.
