Ok, we went over the aluminum vs. iron heads in another thread(which I learned alot from).

Now how about aluminum vs. iron intakes? Specifically for a Windsor. Do you run into the same problems? Or is it a win/win situation with intakes(cooler running/lighter weight)?

I'm not all that concerned with weight savings on my 68 F-100 because it won't be a racer. I've pretty much decided on keeping iron heads, but it looks like pretty slim chances of finding an iron "performance" intake.

Aluminum Intakes are a win-win.

Joe I think the RPM intake is one of the best all around intakes there is.

You can't go wrong with an aluminum intake. I like the Edlebrocks, but some claim that the carb-mounting flanges on the drivers side are cast too thin and can cause some performance problems. Personally, I've never had a problem with any Edlebrock manifold, and I have several.

steve'66 Well said. I agree 100%.

Lighter weight.
Keeps air fuel charge cooler.
Easyer to alter.

Depends on the application, small block, big block, tunnel ram, dual plane, used, new, etc. Summit and Jegg's have some decent prices on new ones. You might be able to find a decent used one on ebay.

For a truck with iron heads you probably just want a performer intake by Edelbrock. They are about $160 new.

Single and dual plane refers to how the cylinders are fed from the plenum/carb.

A single plane has one plenum and feeds all 8 cylinders of a V8 with the air fuel mixture. Good for mid to high rpm power.

A dual plane has a divider in the plenum where one side of the carb's fron and rear barrels feeds 4 cylinders and the other side of the plenum feeds the other 4 cylinders. The usual configuration of a dual plane for Ford, is that one side of the plenum feeds two cylnders in the center of one side and the two outside cylinders of the other side. Such as one plenum feeds cylinders 2-3-5-8 and the other plenum feeds 1-4-6-7. The dual plane is best for low to mid range power and throttle response/low speed driveablility.

Some Ford 2x4 intakes and the Blue Thunder 2x4 for the 429/460 uses the front barrel on one side and the rear barrel on the other side of the carb to feed the cylinders in the dual plance configuration. Generally these can be identified when you look at the plenum area and see two holes on each side of a figure 8 shaped hole.

Offy or Weiand made an intake years ago that I guess you would call a dual plane that one plenum fed one complete bank of cylinders of the motor and the other plenum feed the other side.

hope this helps you.

Ok, I just read through the aluminum vs. cast iron head, and was convinced that for me, the cast iron would make much more sense. On one of my earlier career jobs, I did a lot of work installing HF antennas overseas. I learned first hand to avoid dissimilar metal contact due to all the corrosion that would quickly follow. That post kind of came to the same conclusion, but for a slightly different reason (expansion rather than corrosion). Now I'm wondering why that's a problem for heads, but not a problem for intakes?

I have a '93 vert that's my daily driver. It's nearly stock, and I've been thinking of putting some heads on it. I'd also like a cam that puts out a little more juice. I'd even like a little lub-lub-lub tune to it. I was looking also at the Track Heat intakes vs. Cobras vs. Edelbrock Performers, etc. This post seems to be saying that the aluminum intakes are good to go for my application, but I should avoid aluminum heads?

Just making sure I have this story straight!!

what i'm getting is that aluminum heads are ok if you dont mind checking them once in a while. maybe aluminum intakes are ok because they dont have any moving parts..

I live in an area where it does get cold, although not Chicago! Anyway, expansion differences would be an issue here, and my life is crazy with 3 kids, so I don't see me tearing it apart very often. I think Alex's advice on the cast heads is aimed directly at guys like me (Hey, at least I admit it! ).

Anyway, since the underlying issue would be leaking gaskets, I would think the intake might eventually leak also. Although, mild leak on the intake gasket would have the same detrimental effects, I guess. I was just trying to get the full picture!
