If I was done with the 4R100 build for my Cummins, I'd be saying come and get this 2003 V10, but that's taking forever to get to. Almost ready for fire-up of the Cummins though, so that's something!

anyone have a source for an EGR blocking plate for the ex? I can make one easily enough but If I can shell out $10 and have it show up at my house, I'll got that route.

New engine has an all-metal intake manifold instead of the plastic one, but it's set up for EGR...

im confused, that's not all metal, the bottom half is plastic, just like mine, and the elbow to the throttle body on mine is also plastic.

So how was your old one different then?

This one is the one that's on my truck now, with the crossover tube being the only metal part.

the intake elbow on the new one is metal as well. I'll get a picture of it when I get home from work tonight.

without looking at it to know for sure, I'm pretty sure the new one has this lower intake...

That is a 5.4 Intake, to my knowledge the V10 never had such an all plastic manifold until the 3V motors. The plastic ones make better power because they do not become a massive heat saturation once the engine heats up, the all plastic keeps the intake charge cooler.

I have never seen a 2V V10 intake that was all plastic and am looking forward to seeing those pictures of what you seem to have.

Holy trapped heat in the intake runners batman, You definitely do not want that all metal intake if you want to be efficient and get the most power, that thing will heat saturate like a mo, that is why they stopped doing that.

That almost makes me wonder if they didn't actually sell you a 98-99 spec engine, you might want to check the head casting numbers before you dig into installing that thing, if its a NPI you will have even less power then you started with...

I'll definitely have to look a little more closely when I get home... If nothing else I've got the plastic intake parts from the dead engine I can swap over after giving them a good cleaning.

I'm not really in a spot where I can just... not use the engine that I've bought.

Right, but my concern would be this, if the castings confirm that engine is a 98-99 non-pi motor, does the tune and ECM line up properly, or does it run "wonky" because the heads were more restrictive with less flow, and i think the cam profiles were slightly different as well.

I have no doubt it will fire and turn over, but will it run properly, is a whole different question. I would hate to expend the time and labor putting something all the way back togeather, just to find out it isn't right, i have done that once already.

The air traveling through the manifold doesn't spend enough time in the actual manifold to truly heat soak and cause a massive loss in power. Yes there is difference, but its on the order of 0.00001% .

The reason the OEM's went to composite (or plastic) manifold is the exact same reason that OEM's do most things, cost. A plastic manifold is way cheaper than a cast aluminum one, especially with todays aluminum prices and with the modern advancements in plastic moldings.

If plastic was that much better, then there wouldn't be 500 different metal aftermarket intake options in the LS gasser world (because Chevy LS is were the aftermarket companies invest their R&D money/ time, until the next big thing comes along anyway).
