I learned from one of my previous posts about my casting numbers that I have a 428CJ intake on my 360/390 (I haven't measured the stroke yet). Last night I found a 428CJ intake on ebay that sold for $539. Is that a typical selling price for these intakes? Is my intake worth $539?
When watching stuff on ebay, you cannot always rely on the final bid price. You also must look at the high bidder's feedback. Little or no feedback and there's a good chance the bidder will stiff the seller. Final price is also determined by the item being seen at the right time by the right bidder. The high bidder might have bid up that much for a "correct" date coded part. The same part might not always go as high. Me personally? I wouldn't pay that for a factory 100 lb iron intake. I'd go buy a repro new Blue Thunder 428CJ/PI-427MR intake before considering the iron version. These sell in the $400 range as do the original factory aluminum intakes.
That is an unreal amount of money spend on an iron manifold! From what I can see, one guy wanted it real bad. Most likely because he needed that mainfold due to the casting date making it correct for his numbers matching car. I tried selling my 5-6 years ago on ebay and couldnt even sell it for $50 due to the $100 it would cost to ship it.
Dont get me wrong the CJ intake is a great piece and in the past would bring big money, but this is the time of excellent aftermarket aluminum intakes that out perform the CJ iron. So it basically comes down to how badly someone needs a date specific engine part. You should see what those chevy guys pay for their crap. They not only need a very specific vehicle casting number, but also need the correct date as well.
I have to agree on the above statements. And to add either there were 2 guys who really needed that date code...or it was shill bidded against one honest bidder. For the most part the iron CJ intakes sell for $200-300. Price has gone up on these as well as other R and Q code parts. Last year the norm was $100-150. So the date code of the intake can be key to the selling price sometimes.
Thanks for the info guys. I may try to sell mine someday so I can buy an aluminum intake and fix my port mismatch problem... or I may just keep it if the engine runs well enough with it on there.
I know very little about these engines as I'm a newbie and still learning the basics, so I'm going on what I've been told.
I have D2TEEA heads on the motor.
Here is a quote from my casting number post
Congrats on the intake, other than it's weight, it's one of the better FE intakes. You've got a bit of a port mismatch though where the intake meets the heads. The CJ ports are deeper than the ports on the D2TE heads.
That's what I was asking...what you meant LOL?? All the CJ heads I've had were lowriser port sizes. And the intakes are closer to a MR port size. That's what the CJ was basically. A mismatched intake and port design. TASCA Ford was the first to put a PI intake on a set of 427 lowriser heads thus the CJ coming to the light. Port mismatch and all.

G.
The 428 CJ and the PI intakes have Identical port sizes, at least according to the Ford Performance parts book. The 427MR head ports are 1.34"X2.34", the same as the CJ heads. The 427MR intake is 1.24"X1.94" the same as the 428 CJ and PI. So where's the difference?
The dimensions in that book are full of errors. I'd never rely on that as a source. First hand knowledge only. Been so long since I had a look at the one 428CJ intake I had, I don't recall what ports it had. The 7 CJ heads I had, all had lowriser dimensioned ports.
Dont get me wrong the CJ intake is a great piece and in the past would bring big money, but this is the time of excellent aftermarket aluminum intakes that out perform the CJ iron.
I don't think this statement is right. Although it's been few years, I read a magazine article where they swapped an iron intake for an Edelbrock aluminum intake and lost horsepower. They justified the swap by comparing the weights of the two parts. Go figure.
Either way, I doubt you can improve on the iron CJ intake. Keep it and use it.
