exhaust manifold

[bigbenrusky]

well i am changing my 305 motor to a 350 due to being cracked. now my problem is that the exhaust manifold is cracked as well. can i go with the same manifold with the 350 or do i need to get a different one to fit the engine?

Re: exhaust manifold

The manifold that fits a 305 will fit a 350, they are both small block chevies. But your current manifolds are junk right? So you're gonna buy a new set of manifolds, right? When you look them up on here and elsewhere, it's pretty self explanatory as to what ones you'll need.

Re: exhaust manifold

As I noted in your other thread about "enhancements" GLM makes some "tuned" manifolds that were designed by Dennis Moore. You can get them in either Iron (like your originals) or aluminum to save weight, but I would not even think about the aluminum ones if you will be in salt water.
