Come on 454/502 efi/mpi gen 5/6 fits all bbc intakes, I have used these stlye on dart/hardin/gm intakes they fit all.
Two hose outs so you don't have the mess like gen 4 housings w/r hoes going to exhaust, much cleaner look.

Were just sandblasted/ and mercury enamble painted. Mint cond,look brand new.

I have to see what I have now, think mine look different my 454's are 91's

U have the 4 hose setup, easy swap. They wil fit.

how do you go from 4 to two hoses??? Also do they take the same thermostats, because I already have the kits to replace them on the old ones

Ttt

Instead of two hoses going to your exhaust manifolds just one goes to either side and go in at bottom of manifold. Yours shold have one hose that goes to top riser, that you take fitting out and put a plug in. That how merc does it since 95 or so....same theemostates
