and 400 bucks for a fully plumbed manifold with injectors, damn. wish i didn't live in communist wisconsin!!
ya the link is not perfect, just go down to the two marine mpfi manifolds.

They have been discussed B4. Im sure someones done it. Most do the Edel and add injector bosses. Its a cool manifold and I wish we had that type of injection system.

i didn't find anyone that did it. i really would like to know if it makes more power. because in marine applications, don't they rate it at 230hp?

The MPFI conversion doesnt generally "make power". Normal gains are in the 10hp range. Its the ability to fuel boosted setups better that makes it a huge draw

UR50SLO on syty.net and s-seriesforum did the marine intake conversion without a hitch on his turbo Jimmy. The only issue was that it was heavy cast iron instead of the aluminum 2114 conversion

A note also is the base of ours is aluminum with the plastic upper and the Marine is iron with a plastic upper. Porting is a bit harder and adds weight.
I still like the outside mounted injectors and regulator tho.

The v8 guys are big on that conversion. Most of their information applies to our trucks. The only good thing is you can swap to bigger injectors on it for when you turn up the boost.

Oh, and the extra power, the marine 4.3 has higher compression.

apparently the floor of the marine manifold is a good design for boost as well
