Value of an Original Crossram Intake

Thanks guys. Here are a few more pictures of the areas I think were requested. I plan on sending the intake out to have it authenticated. I just wanted to make sure there was nothing obvious that jumped out before I went to the trouble and cost of doing so. Thanks for all the input.

Hey Jason...I am no expert on x-rams...I'm just comparing your pics to other original units...I have an NOS xram top plate...It is dated exactly the same day as yours!!!

I also have a used lid that is dated one day prior to yours...Upon reviewing my xrams, it seems that the intake lids that are dated in this time frame, have the date stamped in this same area...atleast on the day of your intake and one day prior.I have 2 intakes whose lids are both dated one day apart in Dec. 68...and the dates are on the other side of the underneath of the intake...opposite the vacum hole...and the repro that I purchased for comparison is dated one day prior to yours(just like my other original), but the date code is actually in the wrong spot...it is locted same as the 68 dated intakes...Wow...Did you get all that?

Anyway, your date is very similar to mine..I will try to post a pic...

As for the machined surfaces...the repro I have seems to have small swirl marks where it was machined with a small type bit..or cnc machine? All the origionals have more smooth surfaces and barely any visible lines...on the edge of the top...If you look more on the side just below the carb flange...the originals all seem to have been grinded or finished off abit with some sort of a machine that maade vertical lines...these lines continue around much of the edges of the top of the originals...kind of like they were trimming off the extra flash after the mold...The repro I have has no marks whatsoever....i hope that helps...if you can post a pic of the edge just below the carb flange, ill tell you what I think...and Ill try to post some pics soon too...for comparison s sake...

But do remember...I have not seen one of heartbeats intakes...the repro I have is from the other guy......Does anyone have any pics of the date code on the Heartbeat unit to compare??

Wow, you know your crossrams. Are these the machining marks you are talking about?

Thanks,

Jason

Those are from cleaning up casting flash with a belt sander...

Hey Jason...yup those are the marks I was speaking of....The repro that I have does not have them at all..

Not that my opinion really matters, but Im convinced 99.9% its real....

One other thing to look for are very small stamped numbers near the winters logo and the casting numbers...apparently they are inspection stamps...You have probably already checked Wayne Guinn's site, but he has photos of these small numbers there...typically a number '7' about a quarter inch tall or 3/8's inch tall... If you have not, please check his site...HE is THE expert on these intakes!!

heres a link http://www.guinns-engineering.com/Do...Components.htm

As far as value???????Un fortunately the value has surely dropped, as I saw complete setups in the 20k range a few years ago...now??? Probably get just about half...although I suspect REAL dated carbs would make the value of a whole setup go up considerably as I do recall a set of NOS carbs selling for 12k...apparently, the carbs are much easier to tell the repros than the intakes..I am probably the most upset about the repros, because I bought a handful of these original intakes over the years...

I know someone that bought one recently in the 5000.00-5500.00 range.

Unfortunately, I do not have the original carbs. The carbs that came with it are non original style replacements. I've already talked with Jerry Macneish about having the crossram inspected. You his opinion carry more or less weight than this Guinn's Engineering?

Thanks,

Jason

It was for a bare intake.

Hey Charlie, Was that for just a bare intake?? or a complete set up with original carbs?? I'm getting sadder

Its probably time to sell all my rare stuff before they come out with everything repro...(if they dont already)

I cant imagine in 10 more years when all these repro intakes, distributors, alternators, etc. actually look real old...and resurface as originals...its actually already happeneing everywhere....

I do not see the "7" but do see various small stamping in various areas of the intake. The is a small spade stamping by the lower intake part number which can be seen in the first set of photos I posted. Would Jerry Macneish be a good choice to have varify the intake as original?

Thanks,
