Hey, I picked up a set of Indmar exhausts for my BBC. The type that exit out the top rather than logs and it also eliminates the snails(Ive got Hardin logs with snails now and small hose/tips). The Indmars have 4inch hose and tips.
What I am trying to figure out is if the exhausts are worth installing. Im going to have to redo my engine cover to clear the exhausts and I am going to have to cut some larger holes in the transom.
Right now I am running a basically stock 454. Im running a 21ft jet with Berk JC-A pump. Im WOT in the low [email protected]
What gains can I expect to get?
I remember an article awhile back that compared exhausts. Anyone have that article that can scan it to me?
