I thought he could make a new 83mm butterfly valve in place of ours 4.2 sc engines. Obviously, plug and play with all the electrical connections. We should just enlarge the manifold ....

if he has some requests, he will do it

 

Is the larger butterfly valve a power adding mod, or does it just change response? What about the manifold?

 

is a power adding mod ( like when jaguar users send to maxbore their butterfly valve to enlarge it ) . The manifold needs to be worked.
