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".

C7JE heads and Intake info tor the 427

Response to Carburetor Tilt Shim vs Angled Intake Flange

Well I know the Q series intakes are all angled but none of the F series are, they're all standard SBC intakes. I had to use a wedge on my 20' Sea Skiff inboard application only because the #1409 Edelbrock didn't like sitting at that steep of an angle. On the 38 Commander, I don't believe there is any need for a wedge but it probably wouldn't hurt.

Here is a 390 T-bird intake, C4SE-9425-A This is not an industrial casting, and it has the same tilt. Therefore I don't think the C7JE intake 9425A is a specific marine part, but just an example of Fords "parts bin engineering" which was actually very good.

The C7JE designation indicates a INDUSTRIAL (marine) application on the parts that came from Chris Craft.

C7JE heads are a lowriser style, almost identical to the C6AE-R heads except the exhaust valves have rotators, the two-piece retainers. Chambers are the old D shape 71-74cc, 2.03 intakes and 1.56 exhausts. Exhaust ports are the early style high exits, there is an anti-reversion lip on the top that can be ground out. These heads were standard on Cris-Craft 300 horse 427 engines. It's suppose to be a good flowing head.
