Marine Intake Swap with a Twist

Same foundary that made SLP TPI runners, lol.

But that is an Indimar Marine manifold.

You've got two manifolds in this thread...

You lost me... what is this other manifold?

The one off a Indimar MCX around 2010 year model.

Both are the same lower manifolds. Just have different plenums. There are two different upper plenum designs for it. Both are Indimar Marine manifolds just different year models.

I'd skip the chrome and try vapor blasting. f you're not familiar with it, it's a super fine wet abrasive and is supposed to be fairly corrosion resistant.

I am planning of Mercury marine black paint to make it hide in the engine compartment as much as possible. Possibly LT4 intake red. Just cannot decide which.

This is the new fuel rail design for that manifold. Clears a vortec distributor but not sure about a GMT400 firewall. I have more room though in the Express van and will slap a quick connect to AN adapter and an AN 90* fitting on it.

Michigan Motorz sells this rail and its stainless so it will be E85 compatible.

I just hope a 1991 Caprice thermostat housing fits it and allows me to keep my stock upper radiator hose routing.

I already have the compressor bracket modified and the compressor mounted on a 1/4" piece of plate steel to move it out and up for tall valve cover clerance.
