I love this thread.....laughs. It goes to prove that not everyone has the same interpretation of

what an Imperial should be or look like. Some of us have a narrow interpretation and may only like 2 door cars from a particular era, whereas some may like 4 doors that are souped up.

I recall making a snide comment on a Riviera email list when several members were making fun of a neon pink 73' boat tale Riv. I have never cared for the look of post 68' rivs, esp. boat tales, so just to stir things up, I said "are we commenting on the tacky body style or color?"

needless to say, I was quickly rebuffed.

I have kicked around rebuild options for my 392, moving it up to stock 300 dual 4 status, but had to remind myself I am not 18 anymore, members-only jackets are no longer in style and I will probably not be trying to take out any Camaros with this sled.

Hola All

This series of posting on alum heads, alum intakes and the such seems use-less to me as some another's have already stated.

Other than some lessor pounds of weight ( less some 10 pounds vs the 5,000 pounds of the vehicle ), what is the advantage over an OEM factory intake and the power or torque produced at the user RPM's or MPH. Case Closed. Do they produce power & torque where you drive at, or at the mid to upper RPM's ??? Case Closed.

If one was to go beyond the original heads of the 375 horse powered 440 and the feeling of greatness of the first heads of that era, and move on to the last series of heads the MoPar Engineer's had issued. The MoPar Performace Tech Line will also state the last series of heads flow better than the 1967 era heads. If you was to compare the last series of 440/400 heads with the cast number ending in 452 with the older heads on an flow bench, then what.

If you was to port any of the OEM 383, 400, 413, 426 wedge or 440 heads that you already have of any year with MoPar's P4120437 Porting Template and compare them with a set of E-brock Alum heads on the flow bench ... and cost, then what. Case Closed.

Another mix-match is using the P4452783 cam assembly when there is the P4286675 cam assembly waiting for you at your driving speeds.

When you get dressed to go out for the evening do you wear poka dots and stripes just because the both fit ??? The Alum heads, alum intake and etc will make an difference on an much lighter Dodge Dart being used for the drag strip, But this is not an Dart Drag Strip Site.

The weight advantage on our cars is mainly the ease of installation; for the same reason, I never put back iron intakes on my cars. If I pull one, an alu intake goes back.

And come to think of it, now there are also alu heads which are identical to stock heads on the outside, and will work with stock intakes and exhaust manifolds, check www.440source.com

Other brands alu heads will require some or more modifications. Indy heads wont work with stock intakes, Edelbrock heads do but have spark plugs unaccessible if youre not using headers, B1 are full out racing heads, etc. But if youre into serious performance, aftermarket heads are a must. The flow from stock heads is limited. Also, rebuilding a worn out 40 year old pair of cilinder heads will cost more than a set of new Edelbrock performer heads (depending on where you live, in Europe, decent machine work is very expensive). And remember that the 915 and 906 heads were very fine performance heads in the sixties, but Big Block Mopar technology steadily advanced since then.

But on a stock engine, alu heads offer no real improvement. For blocking the exhaust crossover, there's a nice valleypan gasket set from felpro, cheap and very easy to install.

Maybe I spoke too soon on that?
