CHRIS CRAFT COMMANDER FORUM ® .......A photo-intensive technical reference file and ongoing newsletter regarding the original fiberglass Chris-Craft Commander series. This is an independent not-for-profit and non-commercial web site, not affiliated with the Chris Craft Commander Club ~~ or ~~ Chris-Craft Corporation. Our mission here is to "have fun and share information" about the Commander series (and those associated fiberglass boats on the Chris-Craft family tree) for your individual personal use, and by doing so help promote the good name of Chris-Craft, and help preserve, restore, and appreciate Chris-Craft boats. The main reference feature is the ever expanding MASTER INDEX File which contains what we believe to be the world's largest collection of documentation photos and technical information on the Chris-Craft Commander line of boats, (like these original brochure scans, featuring the iconic first 38 Commander styled by Fred Hudson, and many of the great Dick Avery renditions that followed) , (a huge collection of Chris-Craft 427 tuning and specification information), and a few words about how to use the forum.

We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".

Standard cooling 427 guys, this is what you must do to install the DUI system

Response to Several of us barked.........at the moon.......and at each other, ha!

Here are a couple more photos of the Standard Cooling System (note: the Closed System requires the grinding of the throttle plate but
everything else fits without modification). While this looks pretty simple, and it is, the actual discovery of just "how" to do this
was a bit tenuous, because I ordered the distributors thinking they would fit and discovered they did not after they were custom built
for me. Thankfully, the modifications turned out to be so simple.

Along with the grinding of the stock throttle plate, the T-fitting has to be rotated 90-degrees out of the way and you have
to make up the difference with new plumbing. As you can see in the earlier postings and these final shots, I chose heavily
prepped and soldered copper pipe that was not hard connected to anything, rubber isolated on both ends.

The result is a fire breathing monster that has spark plugs gapped at almost twice their normal gap.

So far the boat has not missed one beat since the installation, these distributors are great.

Regards,

Paul
