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".

Intake clearance issues to check, more than just the carb height in the motor box

Response to Edelbrock 7101 Thoughts/opinons?

These intakes can (and will) make a difference, and with some of the lower powered motors it will potentially make more difference than the high performance motors because the latter may have already come with a performance intake.

Here is an example of what to beware of...........not sure this applies to your motor but I think you'll get the idea.

Note this FLV and pay special attention to the thermostat casting. See how it fits nicely within the limits of the intake casting?

Now look at what I think it an aftermarket intake with taller dimensions, note the same thermostat casting.

It appears to me that the thermostat has been placed on a (custom made?) pedestal in order for the cooling hose routing to still work with the higher rise intake runners.
I don't know this for a fact, but these are the sorts of things to watch out for if you do make a swap for an intake, and also beware if you go for the DUI ignition system
too, those are big and need a lot of side clearance. This may be a GM performance intake, but the Edelbrock RPM would be very similar. I don't know if those thermostat
lift castings are something of a CC part or whether the guy made his own, both are possible.

Other than the fit and clearance issue, also beware if your motor is a Q series because then all bets are off as you'll need a lot of hose and water pump adaptation work,
but once done the motor would probably love the intake. After installation I would watch plugs to be sure you have not created a lean condition, but probably will be good
to go !!
