Hey guys - We've been enjoying our 1996 SeaRay 175 project for a few seasons with the older 4.3 2 bbl. that the previous owner installed. That install came with some "creative engineering" in wiring, shimming pullies for belt alignment and more.....We've really enjoyed boating so I'm going to de-cobble it and set it up right. Many of the original brackets and such were included in a box so I have a fair bit of the original bolt-on's.

After a bunch of research and reading on forums like this, I built a fresh 4.3 Vortec for it similar to what is supposed to be in it. It also came factory with a 4 bbl so I'm making that change too.

I'm down to the intake and the two options are the cast or Edelbrock 2114. I'm set on the Edelbrock because I have the 1409 carb to go on it but there has been no availability and not looking like it until mid-June and that's always a maybe. So...in the interest of time (I'd save a few bucks too but not a driving factor), I'm thinking about going with the cast manifold.

My question is, and I suspect it is probably minimal, but has anyone switched from cast to the Edelbrock as an upgrade that can speak to noticable differences in how the boat runs? Sure, I'll drop some weight and it the Edelbrock will look pretty sweet sitting in it but anything on the performance end?

....anyone have a 2114 they'd sell to me? I'm looking. :) Thanks!
 
Decided to not wait and went with a cast intake. Thanks for the post!
