Exhaust Manifold Compatability Question

[PeteA216]

Hey everyone,
I was wondering, on the 305's and 350's in Caprices in the mid '80s, is there a difference in the exhaust manifolds? (Do the manifolds on the 350's have better flow, or are they exactly the same is the 305's manifolds?) Also, if I were to aquire some manifolds from a 350 in a Caprice, will they bolt right onto a 305? Thanks!

same

80 and up anyways

80 and up are the above spakr plugs straight back along valve covers manifolds,

same for 305 267 350 engines nothing different and car ones are two stud outlet vs. the trucks ones that are three stud, but otherwise identical


i dunno why youre so concerned about smogger manifolds ??

yes they will bolt up, worst case scenario is that you cant use last bolt, but thats kinda rar,e but happens now and then due to there being some 7 bolt heads and manifolds out there they made for certain applications

but they wont leak with the missing bolt, it wil be ok, run them metal to metal no gaskets, they do better that way, no gaskets to burn out, it works, trust me, i never use exh manifold gaskets except for on headers
and that works great too, they are stronger than header ones, and not paper crap,




good luck
