The UPS truck dropped off my next project today, apparently (I wasn't home at the time).
This is going to be interesting; once I get the gaskets I need, I'm going to see what porting an aluminum manifold is like.
ed: And they even threw in the throttle-body!

#3, Meh. I looked it over; it's complete. I'm not sure I'm going to use the split-port actuator that's attached to it--I'll probably try to use mine over again (fewer miles on it, I'm sure).
Nothing appears to be cracked or damaged, and these components have practically no moving parts. I'm now waiting on a complete set of intake gaskets, but just based on the one (?) that they left in the box, it's as I thought--the lower end of the runners are pretty sloppy and it probably wouldn't hurt to enlarge them (esp. the short runners).
This stuff will not be going into my car until I get heads/cam sorted out.

Nice floor. I bet your mom would kill ya if she saw that sitting on the floor, cardboard or not. :P

#5, That's a piece of foam, and she didn't really seem to care. :-P

Wow, it was so easy to pull the upper intake off the lower. Just from what I can see, the intakes are indeed very sloppily matched to the gaskets. Also, I'd like to re-iterate how much I hate the EPA. The PCV (positive crankcase ventilation) system hosed down the insides of the runners with oil residue, and there are a bunch of EGR devices inside the lower intake (fortunately, in the long runners, where I don't care about them too much).

Well, the project is nearly finished, and I've done the best job I can. I'm glad that I bought a set of cores from a junkyard rather than trying to port my own parts--it's slow going and the car would've been out of service for far too long. I've just got some sanding and polishing on the long runner part of the lower intake left.

But anyway, first I bored the throttlebody out a bit, thinning out its inlet lip. Then I halfshafted it (the plate for the throttle body goes into a slotted shaft; the shaft itself doesn't really do much except sit there and block airflow).
Moving on to the upper intake, I enlarged the throttle body crossover a little; I'm not sure that I hogged it out quite far enough. I also enlarged each of the runners out to match the gasket that goes between the upper and lower intake manifolds.
In the lower intake, I enlarged the short runners (used only above ~3K RPM) all the way through, removing casting lumps and other defects as well. I enlarged only the "top" of the long runner (where it meets the upper intake) to meet the gasket, but I did not enlarge the "bottom" of the long runner (where it meets the heads) because it is desirable to keep taper to preserve the air-velocity effect that gives me at least some low-end torque.

#9, Still, I don't expect more than a slight improvement because of the other factors limiting my car's NA performance. First, my heads came with excellent intake flow from the factory--stock splitport heads have been benched at ~225 CFM on the intake side, which isn't too bad when you consider all the factors. Exhaust flow is generally poor (~150 CFM) and requires a combination of exhaust portwork and a dual-pattern cam with long exhaust duration.

#10, For the moment, I just intend to finish the intakes and put them on, since (at most) I'd need to buy a lb-in torque wrench and some RTV sealant. I haven't yet decided whether I want to try to do some head porting myself, or pay somebody a lot of money to do it for me. A lot of people on www.v6power.net have had huge gains by switching to a 207/215 int/exh (duration at .050) cam, but I'd need some headwork to even use that--it doesn't take a lot of lift to put my valvesprings into a bind.

#12, Heck, I would've already cammed the thing if it weren't a pushrod engine. (I don't know any real gearheads, and I'm afraid of dis-assembling half of the engine on my own.)
